feat: build commands produces detailed output of what happened (#927)

This is a copy of the PR @MateuszMa created but due to how the
repository was previously organized I needed to create another one
myself.

This PR introduces a new option `-v` to the `ucc-gen build` command
which shows detailed information about created/copied/modified/conflict
files after build is complete.

     Accepts absolute paths as well.
 * `--python-binary-name` - [optional] Python binary name to use when
     installing Python libraries. Default: `python3`.
+* `-v` / `--verbose` - [optional] show detailed information about
+    created/copied/modified/conflict files after build is complete.
+    This option is in experimental mode. Default: `False`.
+
+#### Verbose mode
+
+Available from `v5.33.0`.
+
+Running `ucc-gen build -v` or `ucc-gen build --verbose` prints additional information about
+what was exactly created / copied / modified / conflict after the build is complete. It does
+not scan `lib` folder due to the nature of the folder.
+
+Below is the explanation on what exactly each state means:
+
+* `created` - file is not in the original package and was created during the build process
+* `copied` - file is in the original package and was copied during the build process
+* `modified` - file is in the original package and was modified during the build process
+* `conflict` - file is in the original package and was copied during the build process but may be generated by UCC itself so incorrect usage can lead to not working add-on
