Calculator plugin - Treat both , and . as decimal separators

**Is your feature request related to a problem? Please describe.**

On Flow Launcher, one can either configure comma, dot or system locale as the decimal separator. However it's very common for one to copy+paste numbers from different locales and as such sometimes do calculations using one or the other without changing the locale.

**Describe the solution you'd like**

It would be great if the calculator could treat both as decimal separator and/or ignore any thousands separator. This works like a charm in other launchers like Wox v1 or Raycast without having to configure anything, but I would be ok if the solution here involved a configuration.
