feat: add gr-leo and gr-dl5eu, fix binding hash script for GR 3.10

Add two new OOT modules to the catalog:
- gr-leo: LEO satellite channel simulator from LibreSpace Foundation
- gr-dl5eu: DVB-T OFDM synchronization and TPS decoder

Update fix_binding_hashes.py to search python/**/bindings/ recursively,
supporting both GR 3.9 layout (python/bindings/) and GR 3.10 layout
(python/<module>/bindings/).
