irods: `itree` gives confusing errors for missing data objects and collections

• main
• 4-3-stable
• 4-2-stable

---

We are testing 4.2.11 with iCommands 4.2.11. We observed itree command cannot correctly handle wrong inputs/arguments for options.

[user1@dev-u0137480 ~]$ itree -L 1 0
terminating with uncaught exception of type irods::experimental::filesystem::filesystem_error: could not open collection for reading: Unknown error -310000
Aborted (core dumped)

We see the same for usages below:

[user1@dev-u0137480 ~]$ itree --indent 3 0
terminating with uncaught exception of type irods::experimental::filesystem::filesystem_error: could not open collection for reading: Unknown error -310000
Aborted (core dumped)

[user1@dev-u0137480 ~]$ itree -I alice.txt test.txt
terminating with uncaught exception of type irods::experimental::filesystem::filesystem_error: could not open collection for reading: Unknown error -814000
Aborted (core dumped)

Also, we can say that having a feature to provide more than one argument or patter (regex) to itree -I itree --ignore could be much useful. (Or a possibility to use in combination with --pattern)

Thanks.
