Experimental tsgo support does not work in a monorepo #47
Description
Describe the bug
In a monorepo where each package does not have a separate tsconfig.json file, tsgo emits the whole declarations of the monorepo to the tmp directory.
I included 3 packages in the reproduction to demonstrate this:
my-package: the problematic packagemy-working-package: has atsconfig.jsonfile in it's root withtsgoparam set to"."my-working-package-2: uses a relative path astsgoparam to the monorepo root
I just added a log to the handler to see what's going on in the output below:

My other observations:
tsconfigRawis ignored- I think
--noCheckflag should be enabled as thetscdoes not run type checking either
