Description

Allow explicitly setting compiler options instead of using rest syntax. This is less confusing in documentation and rollup config. It is also less fragile.

An alternative (see rollup-plugin-typescript2) would be to pull all tsconfig overrides out.

{
...
tsconfigOverrides: {
    compilerOptions: {},
    include: [...]
  }
}

Please explain the changes verbosely in the PR description. (Please edit your PR to add that) Changing how the options are presented to the user is a breaking change so this will be under a lot of scrutiny. Looks like you have some failing CI tests to consider as well.

Code changes LGTM, it looks like there are type errors causing CI to fail

@jpoehnelt if this gets to 60 days without an update, we'll close this one as abandoned. Please have a look at the CI failures so we can proceed.
