[BUG] Unable to plan on Windows

[MartinPJones]

Describe the bug
On Windows 10, after a fresh install in a virtual environment, the ecs-compose-x plan command fails with the error FileNotFoundError: [WinError 2] The system cannot find the file specified: '\\compose-spec.json'

To Reproduce
Steps to reproduce the behavior:

1. How you installed ECS ComposeX: Through pip in a virtual environment:

venv\Scripts\activate
pip install ecs_composex

2. How you are executing it ? : As a CLI tool in venv, over powershell.
   (venv) PS {mydir}> ecs-compose-x plan -f .\compose.yaml -n {project name} --region us-west-1
3. See error:
   jsonschema.exceptions.RefResolutionError: <urlopen error [WinError 2] The system cannot find the file specified: '\\compose-spec.json'>

Expected behavior
Compose-X should plan out the deploy process to ECS.

Desktop (please complete the following information):

• OS: Windows 10
• Python version: 3.8.3
• If you were doing things from a branch, which one?
  All of this is done from the result of install from pip.

I manually did verify that compose-spec.json is in the location it should be, I'm not sure where the pathing is going wrong as the log says it's validating against F:\Projects\clocker-2.0\venv\lib\site-packages\ecs_composex\specs\compose-spec.json which is a correct path.

Hello @MartinPJones and thank you for reporting this bug.
Well that's going to be an interesting one try and fix considering I do not have access to a windows machine.
I will do my best to figure out what ChatGPT and otherwise answers might help with this.

Sorry about the inconvenience.
