Hello espflash team!

I'm interested in using espflash with ESP8266 modules, but I've discovered that support isn't currently implemented. When I run espflash board-info on an ESP8266, I get the error: unrecognized magic value: 0xfff0c101.

I've done some investigation using esptool.py with the --trace flag and have successfully connected to my chip. The trace output shows the sequence of commands (SYNC, GET_SECURITY_INFO, READ_REG) that esptool.py uses to detect and identify the ESP8266 chip and read its MAC address.

I have the full trace output and have begun to map out the necessary detection routine, which seems to hinge on reading a signature from register 0x40001000.

I am very keen to work on adding this feature and would like to contribute it to espflash. Before I start, I wanted to check in with you:

Is this a feature you would be willing to accept a contribution for?

Do you have any architectural guidance or pointers on where in the codebase I should start looking to implement chip detection?

Are there any known pitfalls or ongoing refactors I should be aware of?

Thank you for your time and for building this great tool!
