Exit Helix in current working directory

[Salman-S5]

Add a command that allows the user to close helix while staying in the same directory.

Example:

• Start in home directory
• Run helix
• Use fuzzy finder to go to different directory
• On exit of helix, stay in the new directory

allows quick execution of files or other operations.

I don't think we can change the working directory of the calling process that is just not how shells work.
