 - Various architectural and standards-compatibility improvements (minor breaking changes):
-    - Added new Console commands:
-        - list
-        - explore
-        - query
-        - script
-        - convert
-        - publish
-    - Rebased Console commands on Rich (nice output in the Console)
-    - Fixed `extract` returning the results depends on the source type (now it's always a dictionary indexed by the resource name)
-    - Enforced type safety -- many tabular command will be marked as impossible for non-tabular resources if a type checker is used
-    - Improved `frictionless.Resource(source)` guessing abilities; if you just like to open a table resource use `frictionless.resources.TableResource(path=path)`
