Script that can find programmer and flash firmware via it. (#2193)
* Init * Fallback to networked interface * remove unneeded cmsis_dap_backend * serial number * windows :( * remove jlink, fix path handling * scripts: program: path normalization * scripts: program: path normalization: second encounter Co-authored-by: hedger <hedger@nanode.su> Co-authored-by: あく <alleteam@gmail.com>
