Changing copier template strings (_endops)

edit ✏️

I was completely stuck for awhile. copier was not replacing my template variables. I found out that adding all these _endops fixed it. Now It will support all of these types of variable wrappers

# copier.yml
_templates_suffix: .jinja
_envops:
  block_end_string: "%}"
  block_start_string: "{%"
  comment_end_string: "#}"
  comment_start_string: "{#"
  keep_trailing_newline: true
  variable_end_string: "}}"
  variable_start_string: "{{"

!RTFM: Later I read the docs and realized that copier defaults to using [[ and ]] for its templates unlike other tools like cookiecutter.
