ENHANCEMENT: Thousands separators cannot be computed in Calculator

### Checks

- [X] I have checked that this issue has not already been reported.

- [X] I am using the latest version of Flow Launcher.

### Problem Description

Flow Launcher 1.6.11 (with Calculator 3.0.3) does not understand `,` as a thousands separator: it does not compute any numbers that have a comma. Unfortunately, this issue makes quick math sometimes difficult.

Windows Calculator adds a thousands separator in all of its results, but copy-pasting those results into Flow Launcher causes the Flow Launcher to no longer compute.

By `,` as a thousands separator, I mean this:

3 *10 = 300
300 * 10 = 3,000

### To Reproduce

1. In Plugins → Calculator → drop-down arrow → decimal separator to Dot (.). That is correct; the _decimal_ separator is a dot.
2. Open a Flow Launcher search. Type in 3,000*4. The result should be 12,000.
3. Flow launcher will refuse to compute the mathematical expression.
