refactor: remove dos2unix

[roleyfoley]

Intent of Change

• Refactor (non-breaking change which improves the structure or operation of the implementation)

Description

• Removes dos2unix from hamlet commands and instead relies on external management of file endings
• Updates readme to use the docs install guide
• Fixes references to hamlet python package in cli

Motivation and Context

The dos2unix package is not installed in a lot of machines and adds an additional requirement to setting up hamlet. Its use has been limited and tools like git manage line endings anyway. Removing this from hamlet itself reduces the complexity in setting up hamlet

How Has This Been Tested?

Just felt like quite an edge case that could be handled outside of hamlet. At the current stage you need to ensure you always have dos2unix installed whenever you want to run any hamlet command.

I think the manageJSON.sh usage is the main culprit there so we could leave it in manage crypto. Still feels like it could be managed as an outside process as part of a custom Pipeline or process though

OK - so let's go with removing it and see what cases come up as a result and make a decision then on how to handle them. Given we require python to be installed, another option would be a simple python script.
