Create extreme packages

[LeeCampbell]

Create extreme packages that are designed for extreme performance cases

• only have a single implementation of a histogram defined
• remove the base class
• only implement the interface
• sealed class with no inheritance
• x64 and x86 (32bit) releases.
• no support for synchronization.

e.g. HdrHistogramLongx64.nupkg, HdrHistogramIntx64.nupkg, HdrHistogramShortx86.nupkg

Test to see if they provide significant improvements in

• footprint (dll/nuget package)
• throughput

These would be targets for either .NET platforms requiring extreme throughput (MMOG, Trading, etc), or that require very small footprint (UWA, RasberryPi, etc)
