Add support for Enhanced L2CAP mode to support GOEB #245
Description
For my use case, I would like to be able to use the Generic Object Exchange Profile (GOEP). According to the GOEP specification, the L2CAP channel must be configured for Enhanced Retransmission Mode:
7.1.2 Flow and Error Control Option
The L2CAP channel for OBEX connections shall be configured to use Enhanced Retransmission Mode
The current l2cap implementation in Bumble only supports Basic flow/control mode and does not support Enhanced Retransmission Mode. Therefore will not support GOEP functions. Please update the l2cap implementation (and test cases) to support ERTM.

Note: I'm working on this issue and hope to have a PR soon. Feel free to assign it to me.

FYI, we will likely soon do a bit of refactoring/cleanup in the way L2CAP is handled. I hope that won't conflict too much with your work.

Will the interfaces to the class be changing?

Hi, this topic is not updated since last year.
There is any planned release in the near future, that implements the refactor you were mentioning ?
Thank you for your work!

I have a PoC prototype, but I found it's not very compatible with the original implementation, so I am still thinking how to resolve this.
BTW, if you want to use GOEP, you may just use GOEP 1.1 which is based on RFCOMM.

The refactor has completed. You may feel free to contribute. Thanks.

Basically done in #779.
