Fast double parser #935

Closed Jolanrensen closed 3 weeks ago

Jolanrensen commented 4 weeks ago

Fixes https://github.com/Kotlin/dataframe/issues/607

Created under csv umbrella issue: https://github.com/Kotlin/dataframe/issues/827

Introduces FastDoubleParser as optional alternative double parser. It can be enabled as experimental option (for now) in ParserOptions.

The configurable version of this double parser was created for us :) and the way I implemented it, it can solve some of the locale-fallback-issues we were facing before. Check the tests I created in this PR for more some examples.

It's also faster than NumberFormat!

FastDoubleParser is also used by Deephaven CSV, which helps with our new csv implementation.

Thanks for the review :) I'll merge it for now so I can continue with the csv parser
