Add "absolute direction" option to sneak emulation

Is your feature request related to a problem? Please describe.
It is unnecessary mental overhead to have to think if ; and , will move forward or backward in char/chars search depending on whether we used s/S, t/T, f/F to search forward or backward. An option to use absolute direction where ; always repeats the search action forward and , always repeats the search action backwards already exists in the original vim sneak, and it'd be great to see it added to vscodevim -- especially given that (I think) it'd not be much work.

Describe the solution you'd like
I'd like to be able to opt in to a flag in vscodevim settings where ; always searches forward after an initial search with f/F, t/T, s/S, and , always searches backward.

Describe alternatives you've considered
There is a clever-f implementation idea pending for vscodevim, but that's more of a shift than what I'm proposing here.

If this is a duplicate of another issue/feature request, apologies!

Thanks in advance for your consideration --

No files, tests, or entry points are named. Start by locating the handling for f/F, t/T, s/S and the repeat keys ; and , plus the VSCodeVim settings definitions. Done means a setting enables absolute forward and backward repeat directions, with tests covering the requested behavior.
