The 'ImpuestosP' node of the payment complement (Pagos 2.0) is reported with 6 decimals while the SAT expects the amounts to be expressed with the number of decimals supported by the currency of the payment ('MonedaP'), as published in the 'c_Moneda' catalog, for example 2 decimals for MXN.

Steps to reproduce:

- Have an MX Company setup with Quadrum as PAC.
- Create and sign a customer invoice in MXN with a 16% IVA tax.
- Register a full payment and send the payment complement to the PAC.

Issue:

Payment will be rejected
```
Code : CRPER654
Message : El importe del campo BaseP que corresponde a Traslado, no tiene la cantidad de decimales que soporta la moneda (MonedaP)
```

Analysis:

Quadrum recently aligned its validation on that rule and now rejects the document having fields with too much decimals and, currently, fields like BaseP, ImporteP are pinned to 6 decimals in the template.

Reporting them with the decimals of the payment currency is not enough when the payment settles a document expressed in another currency: those amounts are also compared with the ones of the related documents converted with 'EquivalenciaDR', and the PAC expects the values truncated or rounded

```
Code : CRP20274
Extra Info : Traslados: La sumatoria de ImporteDR es mayor al ImporteP 1.30.
             Valores minimos permitidos: Truncado: 1.29 o redondeado: 1.3
```
