Consistent Field Renumbering Implementation

[metda11]

Overview

This pull request implements a new feature to consistently renumber fields across AL objects (tables and table extensions) while maintaining field number relationships between different objects. Especially importend when Transferfields are used!

@metda11 Thank you so much for the contribution an our apologies for the delay.

So if I get the code correctly here's the difference between the current functionality and the suggested one:

Old behavior (processes each file independently):

File1: field(500) → field(100), field(501) → field(101), field(502) → field(102)
File2: field(500) → field(100), field(503) → field(101), field(504) → field(102)

New behavior (uses global mapping):

File1: field(500) → field(100), field(501) → field(101), field(502) → field(102)
File2: field(500) → field(100), field(503) → field(103), field(504) → field(104)

Correct?

@dsaveyn, yeah that looks great!, The important thing is that the transferfield functionality still works properly!
