Big value handling

[ajunge]

Some claims are very big so a bigger field is needed

@mirceanis this is a potential breaking change for anyone with existing databases. Should we mark it as a breaking change and increment the version nr?

Why? I think typeorm manage to upgrade the database schema gracefully

[mirceanis]

I'm not well versed enough in TypeORM to know if this is breaking or not.
How would one check?
I imagine create a daf-based app, use some claims, upgrade daf to this PR, see if everything still works?

If it doesn't work out of the box, then a migration is necessary and if DAF handles that migration, it doesn't count as a breaking change, because the DB schema is internal to DAF.

[mirceanis]

Will merge this in as a breaking change since the schema change is not graceful in all database drivers.

Thanks for the PR
