• Docs have been added / updated (for bug fixes / features)

• What kind of change does this PR introduce?

This PR reintroduces the -i --input-file flag for the upload command, allowing to upload a single binary, according to the core recipe

• What is the current behavior?

You cannot specify a single binary file for the upload

• What is the new behavior?

This command allows the user to upload a specific pre-built binary

arduino-cli upload -b arduino:samd:mkrwifi1010 -p /dev/ttyACM1 --input-file foo.ino.bin

• Does this PR introduce a breaking change?

Reintroduces the flag that was deprecated in the last release (0.11.0)

• Other information:

Please note that the sketch binary extension (.bin in my example above) passed as the --input-file value will be ignored, because the file extension for the binary files is explicity set at the core recipe level for each board.

See for example here for the arduino:samd:mkrwifi1010 board upload recipe, that the .bin file is set explicitly:

tools.bossac.upload.pattern="{path}/{cmd}" {upload.verbose} --port={serial.port.file} -U {upload.native_usb} -i -e -w -v "{build.path}/{build.project_name}.bin" -R

Added some inline requests.

The business logic is OK.

Ok, this one looked easy at a first glance but ended up being very complicated.
We basically have 4 flags to handle:

• --input-dir specified or not
• --input-file specified or not
• path of the sketch specified or not
• running the CLI from a sketch folder or not

--input-dir	--input-file	sketch	run in sketch dir	output
N	N	N	N	error: no sketch found
Y	N	N	N	OK
N	Y	N	N	OK
Y	Y	N	N	error: --input-file and --input-dir flags cannot be used together
N	N	Y	N	OK
Y	N	Y	N	OK, use --input-dir, sketch ignored
N	Y	Y	N	OK, use --input-file, sketch ignored
Y	Y	Y	N	error: --input-file and --input-dir flags cannot be used together
N	N	N	Y	OK
Y	N	N	Y	OK, use --input-dir, sketch ignored
N	Y	N	Y	OK, use --input-file, sketch ignored
Y	Y	N	Y	error: --input-file and --input-dir flags cannot be used together
N	N	Y	Y	OK, use the sketch specified via command line
Y	N	Y	Y	OK, use --input-dir, sketch ignored
N	Y	Y	Y	OK, use --input-file, sketch ignored
Y	Y	Y	Y	error: --input-file and --input-dir flags cannot be used together

auto-approving my changes :-)

tested both with programmer and bootloader
worked as expected
