amqp10_client OTP27 compilation fails

[nuex]

When using the amqp10_client hexpm dependency in an Elixir 1.17.2-otp-27 project, compilation fails:

Error: "Could not compile dependency :amqp10_client"

Earlier output suggests a conflict with OTP27 maybe expression, which is now enabled by default:

===> Compiling src/amqp10_msg.erl failed
amqp10_msg.erl:41:16: syntax error before: '::'
amqp10_msg.erl:55:35: syntax error before: 'maybe'
amqp10_msg.erl:59:46: syntax error before: 'maybe'
amqp10_msg.erl:81:20: syntax error before: 'maybe'
amqp10_msg.erl:145:5: syntax error before: 'maybe'

Setting ERL_COMPILER_OPTIONS="[{feature, maybe_expr, disable}]" allows mix compile to succeed. Maybe the -feature(maybe_expr, disable). module attribute could be added to amqp10_msg so the client can be compiled with default settings?

Recent versions of RabbitMQ can be compiled with OTP27. I guess we should just push a new version of amqp_client to hex.pm - it's been quite some time and indeed the versions available on hex are not OTP27-compatible.
