Use env.var. to pass options, it could be replaced with extra build arguments

Read _arch.txt and use which matlab as fallback.
This could be more involved and use the whole _MatlabFinder logic.

Reuse path info rather than re-reading the file

This PR proposes a minimal implementation of probing matlab installation paths at runtime from the commands in
$PATHrather than at build time (Related to #45):_arch.txtfile if it is in the packageshutil.which('matlab')as a fallbacksetup.pyto build without_arch.txt, e.g. to generate a wheel.I tested it on Linux and it should work on macos.
A more involved option would be to move the code finding matlab from
setup.pyinto matlab-engine and call it at runtime rather than storing the info in_arch.txt+ a fallback usingshutil.which('matlab')
