In some locales, the decimal separators is a comma

[yarkm13]

It seems that the ps command respects locale settings and uses different decimal separators depending on the locale. For example, the Ukrainian (uk) locale uses a comma as the decimal separator instead of a period so CPU and MEM usage numbers are shown as 12,4. As a result, strconv.ParseFloat fails to parse floating-point numbers in the following lines of the getProcessList() function:

cpu, _ := strconv.ParseFloat(fields[2], 64)
mem, _ := strconv.ParseFloat(fields[3], 64)

A more universal solution could involve checking the current locale, determining the decimal separator, or using a third-party module. However, in practice, there are only two common cases: a comma or a period. For this specific use case, simply replacing the comma with a period before parsing should be sufficient.

BTW powermetrics -s tasks didn't respect locale settings and used period as decimal separator.

Fixes #47

Is there anything else that could cause this? I cloned your fork and I still see 0.00 in CPU and MEM usage.

Here is my locale output
