Add an API to get a description of a compression type, and use it.
Add wtap_compression_type_description(), which returns NULL for
WTAP_UNCOMPRESSED and a descriptive string for other compression types.
Instead of checking for WTAP_GZIP_COMPRESSED and appending "(gzip
compressed)", just pass the compression type to
wtap_compression_type_description() and, if the result is non-null,
append its result, wrapped in parentheses, with a space before the left
parenthesis.
