MGCP_Test: Test AMR octet-aligned/bandwith-efficient mode conversion
osmo-mgw now implements a conversion between the AMR octet-aligned and banwith-efficient payload format. Lets add tests for this Change-Id: I050bfeabfb5fdbf986d429eef3af69fe8158d56e depends: osmo-mgw I622c01874b25f5049d4f59eb8157e0ea3cbe16ba related: SYS#4470
