* Bug Fix in `domain` and API changes

Currently, `domain.query_position_to_coset` is not consistent native code in `ark-ldt`. This commit does the following changes:
* change `query_position_to_coset` to `query_position_to_coset_elements`, and make the return result consistent with native code
* add function `query_position_to_coset` to just return generator and offset instead of coset elements. This is useful when evaluating vanishing poly.

* minor bug fix

* update CHANGELOG

* `query_position_to_coset_elements` use `query_position_to_coset`

* Update CHANGELOG.md

* We add a double_and_add method that computes 2 * self + other more
  efficiently than just doubling + addition; this is not used anywhere 
  yet, but I am planning on fiddling with it to see if we can leverage
  it somehow. (See zcash/zcash#3924 for details)

* We handle constant scalars better:
  * We skip the most-significant constant zeroes to avoid unnecessary
    doubling
  * When intermediate bits of the scalar are constants, instead of
    conditionally adding, we directly use the value of the bit to
    decide whether to add or not.

* Add changelog and .github issue templates

* Implement ToConstraintFieldGadget for Vec<UInt8>

* Add documentation and implementation for slice

* Update documentation

* When a group element is a constant, precompute multiples of powers of two, and perform simple conditional additions (no doubling!).
* For short weierstrass curves, addition with a constant now uses mixed addition, which results in lower constraint weight.
* For short weierstrass curves, scalar multiplication now uses mixed addition, saving 1 constraint per bit of the scalar, along with lower constraint weight (at the cost of a small constant number of constraints to check for edge cases)
