Checking for up-to-date pkg versions and update if necessary.

[0danteh]

The update function is a custom script that checks for updates for the installed packages from the packages and aur directories. It compares the local and remote versions of each package and prompts the user to install the updates if available.

To use the update function, simply run it in a terminal without any arguments. It will print a message indicating the progress of the check and the list of packages that have updates available. For example:

$ update
Checking for updates...
The following packages have updates available:
lib1
lib2
lib3
Do you want to install them? [Y/n]

The user can then enter Y or y to confirm the installation, N or n to cancel the installation, or any other input to abort the operation. The function will then call the do_sync function for each package that needs to be updated.
