Add a possibility to hide all fractional zeros on a price axis marks if all numbers after decimal point are zeros

Describe the solution you'd like

Add an option like tryCutFractionalZeros: boolean that is disabled by default. If this option is enabled the library should try to cut non-valuable fractional parts if possible.

I know about custom formatter, but that's not what we need. We want to hide fractional part in price marks if all marks have zero fractional part, otherwise we want to show it
