Helper for cmd-line keyword search

[lambdamusic]

Would be nice to have a little helper for performing keyword searches from the command line.

Eg

dsearch a list of keywords here

=> simply opens up this page https://app.dimensions.ai/discover/publication?search_text=a%20list%20of%20keywords%20here&search_type=kws&search_field=full_search

Building on this (maybe)

• specialised search for grants and other record types
• print out results to console
