Add retries and days-back option for memories-v1

[jjj120]

I added download retries if some problem is raised during the download of an image.
I also added a days-back option for memories-v1, so if you only want to download the newest memories, not all are requested.

And I have another question: Logging in with my austrian number does not work because the google api-key has expired. Does anyone know what could be done about that?

Heads up: the API key in my pull request should fix your login issue #3

@michielree thanks!

My new semester just started and everything is chaotic, but hopefully, I can sort this out next week. You can expect quicker response times after that.

Thanks for your contribution!
How about we use tenacity for retrying, though? Yes, it is another dependency, but would facilitate future changes and additions in terms of retry logic.
If you're not happy with this suggestion or don't want to do it, I'd go ahead and merge this as-is and keep tenacity in the backlog.
