Cast Wavevalue to string with CultureInfo.InvariantCulture Argument

[SonovumRaiko]

Hello John,

thanks for your nice app! Really helpful for exporting clinical data from Philips patient monitors!

Please modify the following lines:

• https://github.com/xeonfusion/VSCaptureMP/blob/f96a199ee1cecd73b513e28a4a9fc47b364d4d09/Class1.cs#L1596
• https://github.com/xeonfusion/VSCaptureMP/blob/f96a199ee1cecd73b513e28a4a9fc47b364d4d09/Class3.cs#L1925

Just change the lines to: m_strbuildwavevalues.Append(Waveval.ToString(CultureInfo.InvariantCulture));

Best, Raiko
