Added support for Base58(Bitcoin, Flickr, Ripple) and Ascii85(default Base85) and the IPv6 Base85 encoding from rfc1924

Handling the case.

Added support for Base32/45/85 encoding and decoding.

In order to be able to determine some variants of formats we added an relax option where we look slightly deeper to se if we see a signature that we recognise (say PDF), but limited to the 1024 first octets if the deep options is not on. If we have both the deep and relax option on potentially the entire "file" is scanned.

Added snappy compression with support for blocks as well as framed and iwa framed, and adding padding frames to a framed sequence.

Added application/postscript and application/sqlite3 to the media types recogised.

Do not unzip files when not needed when determining the openxmlformats.

Added jhn_magic that supports the determination of a file's IANAmedia type
