iTunes commands not working on macOS 10.15.6

[pbnj]

Bug Report

Since the introduction of Apple Music app on macOS, I believe the iTunes commands have stopped working.

Reproduction Steps

$ m itunes status
29:41: syntax error: A identifier can’t go after this identifier. (-2740)
iTunes is currently .
/usr/local/Cellar/m-cli/0.2.5/plugins/itunes: line 30: [: =: unary operator expected

Proposed Resolution

Fortunately, I think the solution is as simple as replacing instances of iTunes in osascripts to Music.

$ osascript -e 'tell application "iTunes" to artist of current track as string'
39:52: syntax error: A identifier can’t go after this identifier. (-2740)

$ ^iTunes^Music
osascript -e 'tell application "Music" to artist of current track as string'

I will continue to test iTunes commands and submit a patch, including to replace m itunes with m music subcommand.

Same issue here:

$ m itunes vol 0
35:41: execution error: The variable volume is not defined. (-2753)
39:45: execution error: The variable volume is not defined. (-2753)

$ m itunes vol up
35:41: execution error: The variable volume is not defined. (-2753)
39:45: execution error: The variable volume is not defined. (-2753)

I think I found the issue. In m-cli's source, the app is references as "iTunes", but has be renamed in Catalina to "Music".

Example:

osascript -e 'tell application "iTunes" to sound volume as integer'

will fail where

osascript -e 'tell application "Music" to sound volume as integer'

succeeds.

Created a PR #158 to fix this problem in MacOS Catalina and above.
Made a copy of iTunes plugin and renamed 'itunes' to 'music'

Great work @VishalBilagi. Sorry it's taken time to get around to reviewing.

How would you feel about putting the two commands together under music, and eventually deprecate itunes?
