Resizing

As noted in the cuprate_database resizing section, builders on-top of cuprate_database are responsible for resizing the database.

In cuprate_{blockchain,txpool}'s case, that means the tower::Service must know how to resize. This logic is shared between both crates, defined in cuprate_database_service: https://github.com/Cuprate/cuprate/blob/0941f68efcd7dfe66124ad0c1934277f47da9090/storage/service/src/service/write.rs#L107-L171.

By default, this uses a similar algorithm as monerod's:

There are other resizing algorithms that define how the database's memory map grows, although currently the behavior of monerod is closely followed (for no particular reason).
