NumberDecimalSeparator at Track/Album Peak/Gain

[m-mrks]

Hi,

Thanks for this great module!

Found a minor issue regarding the accuracy of AudioWorks.Commands 2.2.0's Measure-AudioFile -Analyzer ReplayGain function related to the number decimal separator.

Tested on Windows 11 with PowerShell 7.4.2; the issue only occurs when the decimal separator is not . but e.g. ,.

PS C:\> (Get-Culture).NumberFormat.NumberDecimalSeparator
,

PS C:\> $audioFile = Get-AudioFile -Path 'D:\path\file.flac'
PS C:\> $audioFile | Clear-AudioMetadata -PassThru
PS C:\> $audioFile | Measure-AudioFile -Analyzer ReplayGain -PassThru | Save-AudioMetadata -PassThru
PS C:\> $audioFile | Get-AudioMetadata
[...]
TrackPeak   : 880828857421874987008.000000
AlbumPeak   : 880828857421874987008.000000
TrackGain   : -305455684738429568.00 dB
AlbumGain   : -305455684738429568.00 dB

Expected:

PS C:\> $audioFile | Get-AudioMetadata
[...]
TrackPeak   : 0.880829
AlbumPeak   : 0.880829
TrackGain   : -3.05 dB
AlbumGain   : -3.05 dB

Can you move these System.Globalization.NumberStyles to a "using" at the top?

Can you put this test in AudioMetadataTests rather than a separate file? Appreciated!

Just a couple of formatting changes but your PR looks good! Thanks a bunch for fixing it.
