Parse AMQP payload for Service Bus

[hallvictoria]

Is your feature request related to a problem? Please describe.
To support Service Bus SDK-type Bindings for Python Azure Functions, we need to parse the incoming bytes content from the Host, transform it into an AMQP message, and use that message to create a ServiceBusReceivedMessage object.

Here is an example of the incoming bytes data from the host that contains the amqp message:

amqp_message = b'\x00Sp\xc0\x0b\x05@@pH\x19\x08\x00@R\x01\x00Sq\xc1$\x02\xa3\x10x-opt-lock-token\x98\xfcS\xa1_\xddfIO\x82]\xee\x1b|4<\xfb\x00Sr\xc1U\x06\xa3\x13x-opt-enqueued-time\x83\x00\x00\x01\x8ev\xc7\xdb\xc8\xa3\x15x-opt-sequence-numberU\x0c\xa3\x12x-opt-locked-until\x83\x00\x00\x01\x8ev\xc8\xc67\x00Ss\xc0?\r\xa1 f00d2a33551440389d68e299d31adc7c@@@@@@@\x83\x00\x00\x01\x8e\xbe\xe0\xe3\xc8\x83\x00\x00\x01\x8ev\xc7\xdb\xc8@@@\x00Su\xa0\x05hello'

Describe the solution you'd like
The goal is to construct a ServiceBusReceivedMessage object out of this. azure-eventhub supports this for EventData objects via the from_bytes method created here

Describe alternatives you've considered
We previously used the uamqp library, which works out - we're able to use the Message object to create a ServiceBusReceivedMessage type with all of the expected properties and annotations populated without any additional formatting on our end. However, since the uamqp library is deprecated and no longer actively maintained (and does not support Python 3.14), we want to find an alternative solution to accomplish this.

decoded_message = uamqp.Message().decode_from_bytes(amqp_message)
return ServiceBusReceivedMessage(decoded_message, receiver=None)

Additional context
