Fixes CircularArrayBuffers dependency

[harwiltz]

I encountered a dependency issue when trying to run some experiments that appears to be caused by an update to the CircularArrayBuffers package. My project environment had CircularArrayBuffers@0.1.7 installed and was causing the following error when I tried to run the JuliaRL_IQN_CartPole experiment (among others):

ERROR: MethodError: no method matching _buffer_frame(::CircularArrayBuffers.CircularVectorBuffer{Float32, Vector{Float32}}, ::Matrix{Int64})

You might have used a 2d row vector where a 1d column vector was required.
Note the difference between 1d column vector [1,2,3] and 2d row vector [1 2 3].
You can convert to a column vector with the vec() function.
Closest candidates are:
  _buffer_frame(::CircularArrayBuffers.CircularArrayBuffer, ::Int64) at ~/.julia/packages/CircularArrayBuffers/FWC6A/src/CircularArrayBuffers.jl:70
  _buffer_frame(::CircularArrayBuffers.CircularArrayBuffer, ::AbstractVector{<:Integer}) at ~/.julia/packages/CircularArrayBuffers/FWC6A/src/CircularArrayBuffers.jl:80

The problem resolves itself as soon as I downgrade CircularArrayBuffers.

This is probably more like a band-aid than a permanent fix, its probably just a simple change somewhere. But I'm not very familiar with CircularArrayBuffers so I thought this fix could be helpful in the meantime.

Thanks for reporting. Should be fixed in JuliaReinforcementLearning/CircularArrayBuffers.jl#11

Please update the dependency to the v0.1.8 once JuliaRegistries/General#56499 get merged.
