Adjust CLEM GridSquare registration logic

[tieneupin]

The CLEM can be configured to acquire a second, denoised image set of a position, which is saved in its own folder with _Lng_LVCC (and other suffixes, as we discover them) appended to the position name (e.g., Position 12_Lng_LVCC--...).

Previously, these datasets were registered as separate entries in Murfey and ISPyB, but we have received feedback that where denoised datasets are acquired, the originals no longer need to be displayed.

This PR addresses this request by adjusting the grid square registration logic for the CLEM workflow. If the image set to be registered has _Lng_LVCC in its name and the original, un-denoised image set has already been registered, it will overwrite the existing entry in both Murfey and ISPyB. If the denoised one was registered first and the un-denoised one comes along, the original won't overwrite the current entry in Murfey and ISPyB.
