Purpose: Exogenous information is the set of data that individuals and
legal entities must periodically submit to the DIAN, with different deadlines
depending on the taxpayer's characteristics, regarding transactions with clients
or users of their products or services. DIAN requires exogenous information reports
to be delivered as an XML file. The goal is to generate the most important formats
(1001, 1003, 1005, 1007, 1008 and 1009) as a CSV, so the user can submit it to the
DIAN for the XML generation.

Key Aspects of the reports:
- Each report has a set amount of columns(including categories) that must be displayed
and the columns are position dependent.
- The rows of the report can be categorized accordingly
	- Header
	- AMLs grouped by partner that are not considered minor amounts
	- AMLs grouped in a minor amount row based on the report's minor amount rule
- The minor amount rules are dependent on the exogenous categories

Additional Changes:
Models:
- l10n_co.exogenous.category:
	- Displayed as columns on the report
	- Used as a basis for the minor amount rules in the report
		- sequence: the column position of the category on the report
		- report_type: the report the category is applicable to
		- name: name of the category displayed on the report
- l10n_co.exogenous.config:
	-Defines how each report is used per chart of account
		- report_type: determines which report the config is for
		- exogenous_category_id: the exogenous category used
		- value_to_report: the type of amount to aggregate for said category,
		such as credit, debit, balance
		- concept: the concept if required by the report
		- account_ids: a many2many relationship to chart of accounts the config is applicable to
Relations:
- account_account_exogenous_config:
	-the Many2many relation table between
		- account.account
		- l10n_co.exogenous.config
Currency:
- l10n_co.reports.uvt:
	- Used to compare amounts in minor amount rules
	- A tax value unit used by the Colombian government to standardize tax values
Wizard:
- l10n_co_reports.exogenous_report.wizard: Allows the user to generate the CSV based on the report

Function Workflow:
- Generate account moves using the accounts that are mapped to
exogenous configs
- Navigate to the General Ledger report
- Click on the action cog to dropdown the button, `Exogenous Report CSV`
- A wizard will pop-up to allow the user to select the type of exogenous
report they want to export
- A CSV file will be downloaded onto the user's machine so they can
import the file into the DIAN pre-validator tool

task-5061117

The Federal Tax Authority (FTA) requires businesses to generate a FAF (FTA Audit File) for audit and compliance purposes in a .csv format.  There are two kinds, VAT and Excise. In this task, we aim to generate a successful VAT Audit File, whereas we we will work to support the Excise Taxes and it's audit file in a separate task. This will bring us a step closer to re-registering us as an Accredited Software Vendor with the FTA (https://tax.gov.ae/en/tax.support/tax.accounting.software.vendors/accredited.tax.accounting.software.vendors.aspx).

As per the FTA, "The FAF should be a pure collection of data in the comma-separated values (csv) file format and should be broken down by, but not limited to, invoices, credit notes etc., to give all the required information to FTA to conduct the Audit. The taxpayer should not be able to modify any value in the FAF. The FAF should not be an image file."

This PR introduces a new module l10n_ae_saft which allows the users to export the a FAF .csv file from the general ledger.
