Ignore IDE files

[suhasdotcom]

I've cloned the pygit2 repo as a runnable and testable IDE project and I think many people would want to do the same. Can we have IDE specific files gitignored?

Some simple lines can be added to the .gitignore file:

For IntelliJ specific IDEs (e.g. PyCharm):

.idea/
*.iml
*.iws
*.ipr
.idea_modules/

For VSCode:

.vscode/

For Eclipse:

.settings/

Python related:

*.pyc
__pycache__/
venv/
.venv/

I'd be happy to raise a PR if this change is accepted. What is the preference to introduce changes:

• Fork and PR?
• Branch and PR?
  • If branch and PR then is there any preference for branch-name-format?

Thanks.
