Fixed DecoderConvBock typo in encdec.py and conditioners.py

[Jovonni]

DecoderConvBock is mispelled in several places in the code:

For example:

jukebox/jukebox/vqvae/encdec.py

Line 28 in 7b9d42c

class DecoderConvBock(nn.Module):

and

jukebox/jukebox/prior/conditioners.py

Line 19 in 7b9d42c

self.cond = DecoderConvBock(self.width, self.width, down_t, stride_t, **block_kwargs, zero_out=zero_out, res_scale=res_scale)

But EncoderConvBlock is correctly spelled

i've searched, and no other DecoderConvBock typos

Thanks for flagging this!
Merging as is will break loading of model checkpoint though, as pytorch will have formatted the keys based on the old class names. If we change both the code and the checkpoints, it'll break the code for people who downloaded the old checkpoints.
It might be easier to keep the typo in this case
