775 preload specific messages in fla

[Kwash67]

Preloads successfully; Except i'm not using a separate worker. I just use setTimeout(() => ... , 0). Its simpler.
FLA is much faster now. List of messages that are preloaded can be found in src/fla/constants.js

Also, I changed how data is sent to render process. In order to reduce ipc serialization overhead, i send large numeric data as typed arrays, instead of objects. Improved data transfer speed significantly.

Pull Request Overview

This PR optimizes the Flight Log Analyzer (FLA) by implementing data preloading and improving IPC serialization performance. The changes eliminate unnecessary local state management and introduce typed arrays for efficient data transfer between the Electron main process and renderer.

Key changes:

• Implemented preloading of commonly-used message labels on log file load using predefined label sets
• Optimized IPC data transfer by using typed arrays (Float64Array/Float32Array) instead of object arrays
• Refactored to remove local React state (chartData) in favor of inline computation from memoized values

Also what happens when you try and preload labels which aren't available? I imagine they just get ignored right?

Yes, they get ignored. See below lines 487 to 502 of fla.js, within the getMessage function.
