Fix ABI compatibility with 32-bit VST3 plugins #80

Browse Source 
This would cause 32-bit VST3 plugins to crash in mysterious ways. What
ended up being the issue is that the plugins expected doubles to be
8-byte aligned in structs, while GCC doesn't do that by default in x86
code for legacy ABI compatibility reasons. Figuring out what exactly was
the issue took months, but luckily the fix was to just add an
`-malign-double`!

If you have downloaded the prebuilt version of yabridge or if have followed the
instructions from the [bitbridge](#32-bit-bitbridge) section below, then
yabridge is also able to load 32-bit VST2 plugins. The installation procedure
for 32-bit plugins is exactly the same as for 64-bit plugins. Yabridge will
automatically detect whether a plugin is 32-bit or 64-bit on startup and it will
handle it accordingly.
