This pull requests add support for writing eFuses to all currently supported chips. From reading both the relevant TRMs and the espefuse flashing process I believe that this should be correct for all of them, though I only have ESP32-S3 and ESP32-C3 devkits to test this out with. In particular I think it would be good if it could be explicitly tested on at least an ESP32 as well since its eFuse controller is structured completely differently from the rest, as well as ESP32-S2 just to be sure since it has rather different timing parameters from the rest.


Since I only have a couple of devkits on hand that limits the number of tests that can be done for this feature, so I would appreciate a review and at least a tentative approval before I perform my final tests.
