feat: extended typescript support

[kirrg001]

Problems:

import instana from '@instana/collector';
console.log('instana', instana);
instana: undefined

No declaration file was found for the module "@instana/collector." "node_modules/@instana/collector/src/index.js" implicitly has an "any" type.

Explanations

Typescript could not load our in-code typedefs. We had to provide types files.
We had no definitions for exported functions.

The PR is a beginning. We need to do much more. Raised a new ticket.

Works

import * as instana from '@instana/collector'

import instana from '@instana/collector'

For testing:
instana-collector-3.19.0.tgz
instana-core-3.19.0.tgz

See new test app.
I have added to our test env.
You can simply create a new project with typescript as dependency and build a app.ts.

Suggestion: Can we exclude compiled js files from the code?

[kirrg001]

Yes we could do that. Lets do that after the release 👍

LGTM 🤞
