Config Files Being Overwritten

[blonienc]

Problem: Precommit config file is overwritten in certain circumstances when running secureli init

To reproduce

1. Make a new git repo with a JS file
2. Run secureli init
3. Modify .secureli/.pre-commit-config.yaml
4. Commit .secureli/.pre-commit-config.yaml
5. Check out repo into a new directory
6. Run secureli init
7. .secureli/.pre-commit-config.yaml has now been reset back to the default value

The solution I came up with is to add a new flag for init which prevents overwriting of the precommit config: secureli init --preserve-precommit-config
