[TABJS-14] Support local fetch, diff, and upload of SQL tables

[dtbuchholz]

Is your feature request related to a problem? Please describe.

• It would be very useful to be able to fetch a (set of) table(s) from tableland, and load them locally in an SQLite database
• From here, users could mutate the database, calculate a diff from the original, and even normalize the statements
• After this, users should be able to then "push" the diff to tableland as a set of SQL statements

Describe the solution you'd like

It would be fine if the above things happen less automagically. For instance, perhaps there is a download to SQLite command. Then editing is manual. They could use standard SQLite tools to diff. Then use a custom "check" command to normalize the SQL statements. Then use the previously mentioned run feature to send the new diff commands from a file.
