:pencil: Description

Type: :rocket: feature

This PR builds up on PR #2736. Just like boundary interaction this PR introduces the line interaction data to the tracker.

I have to implement tests for this new functionality

*beep* *bop* Hi human, I ran ruff on the latest commit (3f7a9437cf05410c4d3a7138834638e38376ab58). Here are the outputs produced. Results can also be downloaded as artifacts here. Summarised output:

```diff 3 I001 [*] Import block is un-sorted or un-formatted 2 PIE790 [*] Unnecessary `pass` statement 2 D411 [*] Missing blank line before section ("Parameters") 2 UP004 [*] Class `RPacketLastInteractionTracker` inherits from `object` 1 B009 [*] Do not call `getattr` with a constant attribute value. It is not any safer than normal property access. ```

@andrewfullard Can you look at the segregation of line interaction as before line interaction and after line interaction in the track_line_interaction function and suggest some changes or comments?

Given that you need to detect the line interaction before and after the interaction process, I'm not sure what else can be done apart from essentially duplicating the method instead of having the if else switch.

The reason rpacket_tracker's boundary_interaction tests are failing because both line_interactions and boundary_interactions have a common field event_id more specifically the interaction number. Since, the line_interactions are added, the event_id of boundary_interactions are changed. So, I have to update the regression data for the boundary_interaction.
