Other tools show file spans in format person.cs:10:0:120:0

This has become relevant due to https://github.com/stryker-mutator/editor-plugins/tree/main/packages/mutation-server-protocol which needs file pattern spans in this format.

We want to standardize on this format because other tools that might integrate with stryker will recognize this pattern, otherwise these tools will need specific fixes for stryker-net.
