chore: Enable requesting numeric enums in "transport=rest" responses …

…for services supporting this (#153)

* chore: Enable requesting numeric enums in "transport=rest" responses for services supporting this (Java, Go, Python, PHP, TypeScript, C#, and Ruby), even if they do not yet turn on REST transport

chore: disallow "transport=rest" for services where numeric enums are not confirmed to be supported (except in PHP and Java)
