Enabled OSMoGrid Deployment

[PhilippSchmelter]

Closes #568

This pull request includes changes to enable deployment to MavenCentral and updates to the CHANGELOG.md file. The most important changes include the addition of a new Gradle script for MavenCentral publishing and the corresponding update to the changelog.

IMPORTANT!!: THERE ARE PROBABLY SOME THINGS BEYOND THIS PROJECT, THAT NEED TO BE SET UP BEFORE THIS WORKS!!

Deployment to MavenCentral:

• Added mavenCentralPublish.gradle script to enable deployment to MavenCentral. This script includes tasks for generating source and Javadoc JARs, configuring the Maven publication, and setting up repository credentials and signing.

Changelog Update:

• Updated CHANGELOG.md to include the addition of mavenCentralPublish.gradle for deployment to MavenCentral.

I think mavenCentralPublish.gradle also has to be called by build.gradle for this to work. Check out how it's done in simona, if you like.
