successfully did some basic math and clipped the predicted x0 intermediate for the continuous time case

learned noise schedule seems to be working, allow for one to make the monotonic net learn a bit more slowly than the unet

allow for configuring the hidden dimension of the monotonic mlp parameterizing the noise schedule

complete learned noise schedule for variational ddpm paper, still need to finish cosine alpha schedule in log(snr) form

unet needs to be conditioned on log(snr) in p_mean_variance for continuous time gaussian diffusion

use a non-sinusoidal embedded condition for continuous time gaussian diffusion conditioned on log(snr)

assume when sampling all batch samples are at the same time, and do not noise for the last time step

get working version of gaussian diffusion with continuous time (only beta linear schedule for now, but will eventually contain alpha cosine schedule as well as parameterized, learned monotonic MLP)
