#11: Format snapshots using LF only regardless of platform

[grimsa]

Addresses #11

[metas-ts]

I did the following, all in a cmd.exe shell on windows 10

git clone https://github.com/grimsa/json-snapshot.github.io.git
cd json-snapshot.github.io
git checkout bugfix/11

Then i edited the pom.xml and

• renamed the artifact from json-snapshot to json-snapshot-PR
• commented out the last 3 plugins, i.e.
  • maven-gpg-plugin
  • maven-deploy-plugin
  • nexus-staging-maven-plugin

Then I did

mvn clean install

with mvn 3.6.0

The build succeeded and installed json-snapshot-PR-1.0.15.jar into my local repo.
I then retried the tests whose failing lead me to this issue in the first place and revified that also these tests now succeed (if the -PR artifact).

Note that building the master branch failed, as expected.

I hope this helps with the review, so this fix can be integrated quickly.

PS: for the time being we are using the artifact that I just build, but obviously it would be great for us if it could be integrated soon.
