Equinox v0.7.0

• Multiple bugfixes for differentiating through, and serialising, eqx.experimental.BatchNorm.
  • This is the reason for the version bump: if you are using eqx.experimental.{BatchNorm,SpectralNorm,StateIndex} then the serialisation format has changed.
• Feature: use_ceil added to all pooling layers.
