Update prettytable-rs-0.8.0 to prettytable-rs-0.10.0

Summary:
`prettytable-rs-0.8.0` has unsafe code ([phsym/prettytable-rs#145][])
that is failing the sanitizers. This is fixed in
`prettytable-rs-0.10.0`. Updating `prettydiff` as well because it too
depends on `prettytable-rs-0.8.0`.

[phsym/prettytable-rs#145]: phsym/prettytable-rs#145
