Hi,

First time trying to contribute here, so apologies for any wrong doing.  I
haven't signed FSF papers; would be happy to but believe this may fit in to
tiny patch territory.

This is a feature request to pass custom flags down to the test compile
step in go-ts-mode-test-... functions.  Specifically I wanted to
add the coverprofile argument to unit test invocation.

The attached patch seems to do the trick for me.
