This problem was found by the Trento group.
The rotated em1s from yambopy seems to be inconsistent with that of a native yambo nosym calculation, at least for the case of no spatial inversion (meaning trev is used for the em1s rotation).
In particular, this is the inconsistency:
X_mat_yambopy(iq,iG1,iG2) = X_mat_yambo(iq,iG2,iG1)
which leads to different BSE absorption spectra.
