Binomial Distribution Errors when Probability is Float32

[jacobadenbaum]

MWE:

julia> using Distributions

julia> rand(Binomial(100, .3f0))
ERROR: MethodError: no method matching Distributions.BinomialTPESampler(::Int64, ::Float32)
The type `Distributions.BinomialTPESampler` exists, but no method is defined for this combination of argument types when trying to construct it.

Closest candidates are:
  Distributions.BinomialTPESampler(::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any, ::Any)
   @ Distributions ~/.julia/packages/Distributions/uuqsE/src/samplers/binomial.jl:77

   @ Distributions ~/.julia/packages/Distributions/uuqsE/src/samplers/binomial.jl:100
  Distributions.BinomialTPESampler(::Bool, ::Int64, ::Float64, ::Float64, ::Float64, ::Float64, ::Int64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64)

Stacktrace:
 [1] rand(rng::Random.TaskLocalRNG, d::Binomial{Float32})

This should probably just convert to Float64 if it needs that under the hood, right?
