[WIP] set up tsconfig for tests, write first test for validate config (Happy flow)

[yaka-fi2c]

• support tsconfig file for tests
• write small test for validate config

@SnirShechter need help on being able to import files on AVA test file (e.g import {myProp} from 'myfile.js' its not accepting it with .js

tbd -> fix the file so will be able to import with .js inside AVA

[SnirShechter]

Ava does not yet support ESM. There's an open issue hanging for more than a year and a project with multiple tickets.

I suggest doing one of three options:

• Checking out their progress and possibly find a way we can use esm (seems like they support .mjs, for example).
• Patching up ava (first by ourselves manually in the node_modules, recorded by patch-package, and then submit a PR.
• Switch to a different testing framework
