DOI registry assumes md5 hashing algorithm #435
Description
Description of the problem:
While trying to load a registry from a DOI of dataverse.nl, I realized that they use SHA1. In pooch the hash algorithm is "fixed" to md5.
Full code that generated the error
import pooch
example = pooch.create(
path=pooch.os_cache("example"),
base_url="doi:10.34894/5SOKTV",
