Requirement: Remove blockette support

[krischer]

Simplification of MiniSEED2: Remove blockette support.

[crotwell]

There should be a standard mapping any important information in existing blockettes into the new additional/optional data structure, #14, as required by #7

[krischer]

Summary

(Please let me know if I missed a point or misunderstood something)

This goes together with #14 and #7. Please vote on:

1. Should we remove the abstraction of blockettes and replace it with something in Requirement: Allow addition of arbitrary headers by equipment manufacturers, operators, etc. without the need for authorization or approval by the FDSN #14? (Yes/No)

[crotwell]

Yes!!!

[ketchum-usgs]
