The legacy-to-UMP converter keeps separate RPN and NRPN selector
flags. When a stream changes selector type without sending data first,
both flags remain set and fill_rpn() gives RPN priority, so subsequent
NRPN data is emitted as RPN.
Clear the previous selector flag after flushing any pending parameter
data and before recording the newly selected parameter type.

The sequencer MIDI 2.0 converter tracks RPN and NRPN selection flags
separately. When the controller stream switches selector type, the
previous flag remains set; fill_rpn() checks RPN first and can encode
subsequent NRPN data as RPN.
Flush pending parameter data with the old selector, then clear the
opposite selector before recording new state in both CC and Control14
event paths. Add KUnit coverage for both transition directions,
pending flushes, null RPN, channel isolation, and MIDI 1.0 conversion.
