Memory leak (particles list is not pruned)

[tkers]

Hi! First of all, thanks for creating and sharing this library. I've started using this a while ago and it's been perfect for adding subtle effects to my games :)

However, after adding a lot of particles to my game (for example during playdate.update for a continuous effect like smoke), I realised the particles are not cleaned up properly and the performance starts dropping steadily.

I narrowed it down to the main particles table which adds, but never removes, each particle instance:

pdParticles/pdParticles.lua

Line 30 in 1a2dec5

particles[#particles+1] = self

I'll try out some approaches to fix this and hopefully submit a PR later for this, but wanted to raise this issue in case you have any ideas regarding it already.

Ooh thanks for catching that, I added the Particle:remove() function which seems to do the job but if you have another idea please let me know

(I've had it running for the last 10-15 mins with no frame drops)

also added Particles:removeAll() to prune the list
