Had to upgrade this because the espree used by 14.x didn't support the regex lookbehind.

I updated the test cases to include a semicolon to ensure everything is working properly with it.

The function now works as follows:
- Find the right-most group of variables (it can be a single
$VARIABLEor a nested one (${VARIABLE:-${NESTED:-default}}); - Expand the inner-most variable;
- Repeat from point 1 until no more variables are found;
Example with { VAR1: "var1", VAR2: "var2", VAR3: undefined }
FOO=${VAR1}something${VAR2:-$VAR3:-default}FOO=${VAR1}something${VAR2:-default}FOO=${VAR1}somethingvar2FOO=var1somethingvar2

This PR fixes #73 by rewriting the whole library to use a simpler approach to the problem.
I think the code should be more readable now, and support more use cases.
