Request: Arm64EC triplet (or make this a header-only library)

[Psychlist1972]

Currently the supported triplets in the vcpkg include Arm64 and x64. For the Windows MIDI Services SDK, we also need Arm64EC because that's the recommendation for most DAWs on Arm64 devices.

An alternative approach would be to move the library to just .hpp files so there would be no compilation target issues.

This is in Progress - certainly for translation and utils this is the case. For the MIDI-CI handlers this will be more work :/
