Add FDSN miniSEED 3 format

[anthonydgj]

Adds support for miniSEED 3, which is a data format defined by the International Federation of Digital Seismograph Networks (FDSN) for data collection, archiving and exchange of seismological data.

Testing

Reference miniSEED 3 files used for testing are available in the reference-data directory of the FDSN miniSEED3 repository on GitHub. When a miniSEED 3 file is downloaded, the contents can be printed out in plain text using the mseed3-text tool from miniSEED3-Utils and compared with the deserialization output using Kaitai Struct.

For example, to output the reference file contents of reference-sinusoid-float64.mseed3:

./mseed3-text -d ./reference-sinusoid-float64.mseed3

Which outputs:
