Small improvements

1. Changed the constraints on key type for HopMap to comparable as it should be.
2. Speed up and simplified insertion operation on both HopMap and HashSet.

Added HopMap and HopSet

1. Added HopMap, a hash map based on Hopscotch hashing. It's faster and more memory-efficient than native map, especially in read operations. It's not for concurrent use.
2. Added HashSet, a hash set based on HopMap.
3. Changed internal hash functions and Hasher type.
4. Slight optimizations.

Better memory foot prints

1. Optimized IntMap and BucketMap.
2. Reduced the amount of memory used by IntMap and BucketMap.
3. Reduced the amount of allocations used by IntMap and BucketMap.
4. Added new hashing functions.

Fixed everything related to module names

1. Module names are changed to all lower cases.
2. Fixed local imports caused by module name changes.

Fixed module name

1.Set module name to github.com/G-M-twostay/Go-Utils

Bug fixes

1. Fixed a bug regarding hash distributions of BucketMap/IntMap.
2. Fixed a bug with hash calculations of Maps.Hasher.HashAny.
3. Added some more hashing options.

First release

1. Maps are now in a good state.
2. Trees are usable but can be better.
3. I haven't tested Queues, but should be good.
