Linux support

[tomjnixon]

This should be ready to merge; there are a couple of things still to look at, but these can be turned into issues as it still works:

• [ ] crash in nng expire thread while scanning (probably just takes too long in debug)

• [ ] warnings from cmake install phase, and .vst3 files should be directories containing shared objects, rather than shared objects

• commits prefixed with linux: are only required for linux support

• commits prefixed with ci: are improvements to the github actions script (kept here to avoid merge pains)

• other commits are general fixes or upgrades that i made along the way

Notes:

• I started trying to build this with JUCE v7, but it looks like this is a bit stricter with VST audio bus formats (specifically that plugins can't have discrete channels by default), and seems to have a tricky bug where you end up with missing channels if you disable assertions.
• I've built this with JUCE assertions enabled in debug, and gone through and commented assertions that this triggers. This way you still get most of the checks and can see where JUCE thinks we're doing things wrong. Perhaps this would be a better strategy in general?

For reference, I've been building with:

cmake -B build/ -G Ninja -DEAR_PLUGINS_UNIT_TESTS=OFF -DBUILD_TESTING=OFF -DSMTG_CREATE_PLUGIN_LINK=0 -DCMAKE_BUILD_TYPE=Debug
ninja -C build install

I just tried compilation on my Ubuntu 20.04.

I just tried compilation on my Ubuntu 20.04.

Thanks, but yeah, as mentioned on the other thread it will probably require using vcpkg -- ubuntu 20.04 ships protobuf 3.6.1.3, while vcpkg provides 3.18.0. I'll try to put together some instructions for this next week.

binaural rendering is glitchy (possibly just too slow in debug?)

I think that's probably the case - certainly true when I do the same in Windows
