Add a client for monday.com and expose commands

[viniarck]

Monday will also be used and a new entry point should be be exposed for it:

diff --git a/setup.py b/setup.py
index 2f5914d..a93d8be 100644
--- a/setup.py
+++ b/setup.py
@@ -27,6 +27,8 @@ setup(
         "Operating System :: POSIX :: Linux",
         "Operating System :: MacOS",
     ],
-    entry_points={"console_scripts": "ghs=ghs.bin.cli:main"},
+    entry_points={
+        "console_scripts": ["ghs=ghs.bin.cli:main", "monday=monday.bin.main"]
+    },
     zip_safe=False,
 )

The functionalities, command and which endpoints (with OAuth) will be consumed will be mapped later on when this turned into a higher priority.
