Add validation of gain calibration files for Neuropixels

- Refactored code (moved to helper class) and made names consistent
- Added TryParse for NeuropixelsV2e and NeuropixelsV1e calibration files
- Refactored code to return a nullable type instead of following the conventional TryParse pattern
- Added dialog elements that displays the current gain correction value from the gain calibration file
- Added V2 gain correction class for easier passing of correction and SN
- Display the serial number after parsing calibration files
- Add a button to open a new window for the ADC values in NeuropixelsV1eDialog
- Small update to size of controls and panels
- Added status strip for Neuropixels V1e
