Using read(::IO, nb) returns no data on first read with S3Path

Underlying issue seems to be: rofinn/FilePathsBase.jl#126

[nickrobinson251]

Confirmed that with rofinn/FilePathsBase.jl#140 we now get

julia> using AWSS3

julia> ENV["AWS_DEFAULT_REGION"] = "us-east-1"
"us-east-1"

julia> p = S3Path("s3://fcp-indi/data/test_resources/mpi_smp.conf")
p"s3://fcp-indi/data/test_resources/mpi_smp.conf"

julia> io = open(p)
FilePathsBase.FileBuffer(p"s3://fcp-indi/data/test_resources/mpi_smp.conf", IOBuffer(data=UInt8[...], readable=true, writable=true, seekable=true, append=false, size=0, maxsize=Inf, ptr=1, mark=-1), true, false, false)

julia> read(io, 8)
8-element Vector{UInt8}:
 0x70
 0x65
 0x5f
 0x6e
 0x61
 0x6d
 0x65
 0x20

So this can be closed once there's a new patch release of FilePathsBase with that fix

[omus]

Fixed as of FilePathsBase 0.9.12
