Merge Request: Disable Pre-Authentication Compression Support

Referencing issue #169 (closed) , this merge request removes the support for the Pre-Auth Compression.

Removed zlib (which is the general purpose compression library responsible for preauth compression) from the supported methods.
Updated unit tests to remove the zlib algorithm.
Removed zlib from the wanted algorithms list.
Refactored the compression_enable wrapper function to remove the code handling the non-delayed compression algorithm, which compresses packets pre-auth. Since we will no longer support this type of compression, the delayed compression will be the only supported compression type.
Updated tests

Unit tests have been updated to remove the zlib algorithm. The changes have been tested locally and passed all tests.

None.
