ENH: adds `axial_acceleration` attribute to the Flight class

[Gui-FernandesBR]

Is your feature request related to a problem? Please describe.

Some rockets may present an avionics system measuring the rocket axial acceleration instead of the "ground reference" acceleration.
RocketPy should be able to easily create

Describe the solution you'd like

• Needs to check how to transform the current acceleration components to the axial acceleration.
• A cached property should be created in the Flight class

If the purpose of this feature is to determine the acceleration experienced by the avionics, in order to include the effects of angular acceleration, it would require a parameter for the location of the avionics package (specifically the accelerometer). Maybe have the Cg position as default and look for an Avionics component type?

Hello Eric, thanks for your comment.

I realized the description of this issue is really bad and does not reflect what I had in mind. I will update it asap.

What I meant was to simply transform the acceleration from one frame (earth) to other (rocket). That should be less complicated.

You do have a great point regarding the location of the avionics system. I think im the future we will be doing something like what you've suggested. There's the #sensors issue that is related to this future.
