Seq.chunkBysize exception

[cata]

For certain sequence expressions, Seq chunkBySize throws exception if the resulting sequence is shorter than the maximum chunk size.

Thanks for the report! Indeed, the chunkBySize proxy is calling MoveNext again on a sequence object when it has already ran out, this can fail, and so needs a fix

if o.MoveNext() then

@Jand42 - thank you for the fix!
