Tiling sequence group hard-coded as 1.1

Running tiling from bliss allows to write multiple tiling sequences in the same file.

However tiling sequence scan group is hard-coded here as "1.1": https://gitlab.esrf.fr/ui/daiquiri/-/blob/main/daiquiri/core/components/tomo/scans/tiling_sequence_tomo_scan.py#L29

Maybe using blissdata we don't need to care about this.
