In #16747, the optional arb package is proposed for inclusion in sage.
That ticket did not have any python bindings for the library.
In the present ticket, rather minimal bindings are provided.
As a proof of concept, the digamma function of a
`RealIntervalFieldElement` is implemented by converting it to an `Arb`,
computing the digamma function via the arb library, and converting the
result back.
In its present minimal form, this is not part of the sage coercion world.
