midi: reworked metaevent decoding for PR comments

Browse Source 
- fixed remaining snake-cased event names in tests and examples (cf. https://github.com/wader/fq/pull/1004#discussion_r1737054466)
- report 'status' and 'event' seperately (cf. https://github.com/wader/fq/pull/1004#discussion_r1737085013)
- decoded TimeSignature metaevent as length + byte fields (cf. https://github.com/wader/fq/pull/1004#discussion_r1737105173)
- decoded SequencerSpecificEvent metaevent as length + byte fields (cf. https://github.com/wader/fq/pull/1004#discussion_r1737111253)
- reworked Errorf's as Fatalf's for data reads (cf. https://github.com/wader/fq/pull/1004#discussion_r1737123374)
