Bugfixes

• -1 properly conflicts with the exec family of options.
• --max-results overrides -1
• --quiet properly conflicts with the exec family of options. This used to be the case, but broke during the switch to clap-derive
• --changed-within now accepts a space as well as a "T" as the separator between date and time (due to update of chrono dependency)

Other

• Many dependencies were updated
• Some documentation was updated and fixed
