Add script to retrieve SRA runs from a list of arbitrary SRA accessions

This script is quite simple: it takes a list of SRA accessions (any kind) and
retrieves all the SRA runs that are linked to it, like so:
* study -> experiments -> runs
* experiment -> runs
* sample -> runs

For each run in the final list, the script then prints the linked study,
experiment, and sample in a tab list.
