Formio.js version updates in Windows environments are not available

[niulinlnc]

The formio.js version updates in Windows environments are not available, mainly:

1. The path cannot be found
2. The resource bundle cannot be uncompressed
   Although in a formal environment it will run under Linux. However, in the Windows development environment, it is not easy to update the version.

@niulinlnc yep I understand and even expected this annoying issue and concern.
In past software projects, I always bothered and solved OS/platform differences.
Windows installs were never my concern with odoo-formio, yet.

I would like to solve, or you're able to prepare a PR with improvement?

[niulinlnc]

@bobslee I've solved it. #92

[niulinlnc]

@bobslee There is another problem here. If my odoo server is deployed under Docker environment, the module folder is generally read-only, and permissions will be involved when downloading the version here.

[bobslee]

@niulinlnc Thanks for your PR. I shall review upcoming days.

Regarding the Docker issue...
Can't you add an extra Volume mount?
In case that's not ideal... which path, for downloaded/installed version assets, do you suggest?

[bobslee]

@niulinlnc do you want to solve/improve this Docker / module directory issue first?
Or shall I merge your PR?

[bobslee]

@niulinlnc no need to discuss about the Docker setup issue?
I'm curious if and how you solved.
