- ✨ Enhancements
- Added a new class Daru::Offsets for providing a uniform API to jump between dates.

- Added a new Arel-like querying syntax for Vector and DataFrame. This will allow faster and more intuitive lookup of data than using loops such as filter.
- Vector
- #concat now compulsorily requires a second index argument.
- Added new method #index= to change the index directly.
- Added basic functions for rolling statistics - mean, std, count, etc.
- Added cumulative sum function.
- Added #keep_if.
- Added #count_values.
- Indexing
- Changed Index so that it now accepts all sorts of data (not restricted to only Symbols as it was previously).

- Removed the + operator overload from Index and replaced in with union.
- Removed the second 'values' argument from Daru::Index because it's redundant.
- Changed behaviour of Vector#reindex and DataFrame#reindex and #reindex_vectors to preserve indexing of original data when possible.

- Fixed DataFrame#delete_row and Vector#delete_if.
