{value: ...} syntax needs support

[KaiRo-at]

See https://github.com/ethereum/solidity/releases/tag/v0.6.4
General: Deprecated value(...) and gas(...) in favor of {value: ...} and {gas: ...}

That syntax currently causes failures to run solidity-coverage (using 0.7.2).

Thanks @KaiRo-at, I will add this to the growing list in #481.

It's also being tracked in solidity-parser-diligence 14

Should be fixed with 0.7.4.
