Extend Convert-FromDatanorm with additional record types

[cnEUL]

Extend Convert-FromDatanorm to include additional record types such as long texts and insertion texts. Currently the record types A,B and P are supported, which are sufficient for simple scenarios.
However, the long texts with their insertion options would also be important. The datanorm interface must get the level of the internal datanorm interface in EULANDA ERP.

Through this it is then possible to read in any data suppliers (wholesalers) automatically. The process would have a high user friendliness as a pure server service.
