Consider to support more overloads for serialization and deserialization

[mikir]

Currently, the serialize and deserialize functions works only with zserio::BitBuffer abstraction. This might be inconvinient for users who work for example with STL vectors. Example:

zserio::deserialize(zserio::BitBuffer(zserio::Span(myBlob.Data(), myBlob.Size())), spatialExtentResult);

Don't forget that each bit matters in Zserio and deserialization should always know exact number of bits. If not, then deserialization might possible read the rest bits in the last byte which does not belong to the stream.
