review/delete code called from UCA/Main & UCD/Main dispatch

[markusicu]

We have two Main.java classes that can be called with various command-line arguments and dispatch to other classes. I suspect that some of these are obsolete. They don't show up as "unused" because they are called in the dispatch.

Review each dispatch item and see if we still need that code.

@macchiati could you please help review/evaluate?

• UCD/Main: https://github.com/unicode-org/unicodetools/blob/main/unicodetools/src/main/java/org/unicode/text/UCD/Main.java
• UCA/Main: https://github.com/unicode-org/unicodetools/blob/main/unicodetools/src/main/java/org/unicode/text/UCA/Main.java

Yes, but I'm fully booked for the next week or so. After that?
