`anchorpy client-gen` fails with error: "unknown variant `alias`, expected `struct` or `enum`"

using raydium idl

anchorpy client-gen fails with error: "unknown variant alias, expected struct or enum"

when encountering this in the types section:

{"name":"TickArryBitmap","type":{"kind":"alias","value":{"array":["u64",8]}}}

this error is raised:

/anchorpy/cli.py", line 109, in client_gen
    idl_obj = Idl.from_json(idl.read_text())
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
solders.SerdeJSONError: unknown variant `alias`, expected `struct` or `enum` at line 1 column 20942

using latest version of anchorpy

user error is not out of the realm of possibility ;)
