[CUERipper] Add setting to force ReadCDCommand

The ReadCDCommand is not detected correctly in some cases. This has
been reported for Plextor drives PX-5224TA and PX-708A.

- Add CUERipper setting `ReadCDCommands`
  The setting can be modified by editing `CUERipper\settings.txt`
  Remark: CUERipper needs to be closed while editing the file.
- Values for the drive specific setting `ReadCDCommands` are:
  0 (ReadCdBEh), 1 (ReadCdD8h), 2 (Unknown/AutoDetect)
  Default: 2
