Title: WIP: fixing eigs

First part of fixes for solving the issue reported in #6965:
* default value of `maxiter` reduced (1000 was a lot)
* change `which` specification to use symbols rather than strings, e.g. `:LM` etc
* input preprocessing to transform `which=:SM` into a shift-and-invert method with `sigma=0`.

Remains to be done:
* fix output postprocessing in `eupd_wrapper` to select correct eigenvalues and eigenvectors.

I am to tired to finish this now, will try to do so tomorrow.
