Workspace reorder (#868)

* Try different workspace structure

Move main crate (atuin) to be on the same level with other crates in
this workspace

* extract common dependencies to the workspace definition

* fix base64 v0.21 deprecation warning

* questionable: update deps & fix chrono deprecations

possible panic sites are unchanged, they're just more visible now

* Revert "questionable: update deps & fix chrono deprecations"

This reverts commit 993e60f8dea81a1625a04285a617959ad09a0866.
