Handle standard JSON transalation with `outputSelection` for `=<0.4.19`

[kuzdogan]

We've come across an issue while recompiling a contract with 0.4.19 as laid out here: https://github.com/ethereum/sourcify/issues/1017

TLDR: The compiler gives empty JSON output without throwing because the outputSelection fields were introduced in 0.4.18 and updated in 0.4.19.

I believe the outputSelection field needs to be handled by the JSON translator translate.ts of solc-js for the earlier versions.
