Fix charging controller software version check for BSM-WS36A

[sirhcel]

• There is an issue with checking the controller software version in https://github.com/OpenChargingCloud/ChargyDesktopApp/commit/a21ee7793f5b731dbfd68b97bc520a0cf5d63faa

  • The software version is always checked against the one supplied as CSCSWVersion to tryToParseBSM_WS36aMeasurements
  • Chargy always passed an empty string there
  • So the check failed in cases where a actual software version was set (which was not covered by the test data so far)

• This PR fixes the check for the changing controller software version for BSM-WS36A data

  • Check that the software version is consistent across measurments
  • The parameter is made the expected software version
    • Using null for not expecting a certain software version
    • If specified, the software version from the measurements needs to match

• Test data is provided in analog to #66

• This PR also includes removing the JavaScript bundle generated by webpack from version control
