Discarded default values in enums require immediate reconstruction

[feldentm]

If a block is discarded for an enum, that block has to be reconstructed from the file's default value on read.
This is different from other types as the default value is not not constant for enums.

Note: This is only relevant, if the OGSS least name of an enum member differs for the file and the tool specification.
Therefore, an easy workaround and almost always applicable workaround is not to use change tolerance with enums.

This should be fixed for distributed fields in Java.

The issue should be fixed for distributed fields in C++

[feldentm]

The issue is mostly fixed in C++. The workaround initialization from the code generator should be removed and a proper initialization should be performed by the parser skipping over already initialized blocks. There are comments for this in the code.
