Float64 parsing error

[tk3369]

From JuliaData/CSV.jl#397

Base.parse works correctly but Parsers.parse failed:

julia> Base.parse(Float64, "74810199.033988851037472901827191090834")
7.481019903398885e7

julia> Parsers.parse(Float64, "74810199.033988851037472901827191090834")

I think I have a fix for this locally; adding more tests
