Add PEAQ to FX enc -> FL dec tests

As suggested in https://www.3gpp.org/ftp/tsg_sa/WG4_CODEC/3GPP_SA4_AHOC_MTGs/SA4_Audio/Docs/SA4aA240038.zip,

"

  • The performance of the FX code should match the performance of the FL code, both in terms of subjective quality and complexity. ...
    • For bit-streams generated with the FX encoder, the output synthesis of the bit-stream decoded with the FL decoder compared to the synthesis of a bit-stream generated with the FL encoder and decoded with the FL decoder should be within the limit of MLD < [TBD], PEAQ (basic profile) < [0.1]. "

FX enc -> FL dec tests should be added to the pytest suite. Currently, an interop test is there but it only checks for crashes. The output comparison should be complemented with a PEAQ measurement.
