v1.7.2

MOABB 1.7.2 fixes compatibility with pyRiemann mean APIs.

• Use gmean in TRCA and TRCSP, supporting pyRiemann 0.12 and current 0.13 development versions.
• Pass the TRCSP metric by keyword to fix fitting with pyRiemann 0.12.
• Add regression coverage for three TRCSP metrics and two TRCA covariance means.

This patch release is based on v1.7.1 and includes the fix from #1180. The dependency remains pyriemann>=0.12 from PyPI.

Validated the wheel and source distribution with twine check, the classification suite (31 passed, 12 existing expected failures passing), and SPD Learn integration/geometry tests (380 passed, 146 existing skips).
