[BUG] Default URL cannot be assigned

[patchgamestudio]

Description
When running app.start(), the default URL that Robyn assigns is 128.0.0.1, which appears to be a public IP in the Netherlands. This causes the application to throw the following error on Ubuntu 20.04 (WSL2):
OSError: Cannot assign requested address (os error 99)
Windows error:
OSError: The requested address is not valid in its context. (os error 10049)

Expected Behavior
Most likely, the default URL was meant to be 127.0.0.1 which is the universal address for localhost. When running app.start(url="127.0.0.1", port=5000) or app.start(url="0.0.0.0", port=5000) the OSError is not encountered. Robyn runs successfully on Ubuntu, but still encounters another known issue in Windows.

Environment:
Tested on both Windows 10 and Ubuntu 20.04 (WSL2 on Windows 10)
Robyn version: 0.12.0

Thank you for this bug report. I see some typo crept in the package release. I will fix the code and start a better unit testing system in the next release(also hopefully tomorrow).

Thank you!
