Hasher and dropbox hash support

i have been using the hasher backend which has been great - has really reduced the amount of processing time on backups. we have started to use the dropbox backend for an additional backup. since dropbox uses a different hash method, hasher does not give any gain and it takes hours for rclone to calc the checksums. any interest in adding the dropbox hash as a supported hash type for hasher?

thanks!

I'd open a request on the github:
