Base.read method partially supported

[etibarg]

Hi,

Following logic from #279, in order to add "transparency" in the use of S3Path, I ended up coding the following:

using AWSS3: S3Path
function Base.read(fp::S3Path, nb::Integer)
    read(fp; byte_range=1:nb)
end

... in order to match:

Base.read(s::IOStream, nb::Integer; all=true)

(in a simplified version)

Granted, the Base version takes an IOStream. But considering the existing read(fp::S3Path; byte_range=1:nb) method provided, the expected behavior is not far-fecthed.
This is very convient in order not to download the whole file (e.g. to access some metadata), while not caring of the actual path type.

Would it be possible to implement it?

Rgds,
