Serializing curve elements through their compressed representation is sometime not convenient due to the large computational costs of the "decompression" algorithm of some curve. The serialize and deserialize routines of the c extension 'pairing' now take an additional positional argument to disable elements compression. The corresponding serialize and deserialize methods of the PairingGroup class now implements an optional keyword-only argument 'compression'. The default value behavior is to use compression for compatibility with previous versions.

Added support for uncompressed serialization of PairingGroup elements for faster deserialization (for scenarios with not-so-strict storage and network constraints).
To maintain compatibility with existing schemes, the default behavior of the (de)serialization routines is to use compression. Compression can be disabled by using a keyword-only boolean
compressionargument when calling PairingGroup.serialize and PairingGroup.deserialize.Additionally, serialize, deserialize and pairing product routines now raise standard fine-grained python exceptions (TypeError and ValueError) with more informative messages (especially pairing product).
