ava --init should respect package.json indentation

Description

Running ava --init adds ava to my package.json but also reformats the whole file to 2 spaces instead of the 4 I have listed in my .editorconfig.

# top-most EditorConfig file
root = true

# Unix-style newlines with a newline ending every file
# and trailing whitespace removed
[*]
end_of_line = lf
insert_final_newline = true
trim_trailing_whitespace = true

[*.{js,css,json}]
charset = utf-8
indent_style = space
indent_size = 4

# Matches the exact files either package.json or .travis.yml
[{.travis.yml}]
indent_style = space
indent_size = 2

Ah, I didn’t know that. I think it makes more sense to just preserve the existing indentation though, than specifically read .editorconfig. Could just get the indentation with detect-indent. Pull request welcome.

Would it not be better to add an auto option to write-json-file?
