Update .hgignore

Update README Credits section

Update README Contribution section to fit with Sourcehut's unconventional workflow

Fix the classic a[len(a)] mistake

Add a slash (/) at the end of the directory path in case the custom directory path by the user doesn't include it

Fix another bug in the CLI where the --dir flag uses . instead of ./, resulted in an error when querying a directory

Fix a bug in the CLI where the port default is handled incorrectly, resulted in a wrong --port flag

We still need ACCESSIBLE_DIR though

Remove ACCESSIBLE_DIR and PORT constants since we now have defaults for our CLI arguments/flags

Massive overhaul to help Robin deal with CLI. Robin now can handle custom directories and custom ports

Add the package mkideal/cli to provide CLI for Robin

Remove file size format for directories in folder table

Add nice time format for last modified table

Add last modified date of files to table

s/ByteCountIEC/ByteCountSI/g

GNU dc displays human-readable file size format in SI but for whatever the fuck the reason is they display kilobytes that aren't compatible with SI or IEC, so now I have to do a throwback

s/ByteCountSI/ByteCountIEC/g

Uses IEC instead of SI for human-readable file size format to fit with Linux

Setting default column width can hurt users with different screen size, so I remove it

Set the Name column to be 100
