feat: add home, end, and delete cursor functionality

[BendikMann]

This is a continuation of the pull request @gary7530 initially submitted, but did not complete the merge that @funbiscuit requested.

@gary7530's original pull request:

This commit implements support for the Home, End, and Delete keys to improve command-line navigation and editing.

Home Key: Moves the cursor to the beginning of the command line.
End Key: Moves the cursor to the end of the command line.
Delete Key: Removes the character at the current cursor position.

The changes include parsing the corresponding ANSI escape sequences in onEscapedInput within embedded_cli.c.

Please let me know if any additional changes are required.

Hi @funbiscuit, since @BendikMann has already rebased the changes in #57, we can proceed with that PR instead. I'll close this one to avoid duplication. Thanks!
