add a command to replace a temporary id with a permanent id

[elf-pavlik]

The use case is when some records gains a permanent URL and we need to replace a temporary one generated before permanent one existed.
@jeff-zucker had comment in #76 that should be taken into an account

Exampe

npx catalog migrate permalink --tmp urn:uuid:3b05c17c-f44a-470e-8031-408abee6e2ca --perm http://uu3.org/People/Eric/

@jeff-zucker: I do not approve of "add a command to replace a temporary id with a permanent id". We had previously discussed that this should be applied to new records but that existing records should keep their temporary ids until the new forms are ready. Changing these now will greatly complicate the manual addition of data and AFAIK does nothing to actually make the the data easier to access or edit. Once the new forms are ready, yes then a migration script can be implemented.

I'm not referring here to #7 I want a simple command that given a temporary identifier in data (can be either # or urn) and new permanent URL provided by somone, it will simply replace that old identifier across the dataset with the new one. Do you see any issues with that?

For example someone mentioned by Jesse in #60 replies with their actuall WebID
I added example command to my initial comment.

It make changes to existing records which complicates my update tasks but I guess you need it to validate that webid==id, so go ahead.
