Make it possible to run titiler-cmr locally

[hrodmn]

To make development easier I want to be able to run titiler-cmr locally.

This PR adds the following:

• expanded README
• fix a few deprecation warnings
• upgraded dependencies
  • titiler>=0.17,<0.18 -> titiler>=0.18,<19
• option to retrieve asset links with https instead of s3:// and use .netrc for authentication and a few tests

@vincentsarago I added one more change after realizing that fsspec needs a little extra help opening files over https if there is any authorization required. Fortunately the earthaccess package provides a helper to configure a fsspec filesystem that has auth worked out already.

If e95d39c looks ok to you then I'll go ahead and merge this!
