* Bump the dependencies and remove patch
* temp remove dev-dependencies (until curves are published)
due to circular dev-dependencies
* bring back dev-dependencies
to be merged only after curves crates are released
* bump patch version
* fix
* use frobenius_map_in_place instead of frobenious_map
* temp remove dev dependencies
* chore: Release ark-r1cs-std version 0.4.0-alpha.2
* Revert "temp remove dev dependencies"
This reverts commit 6b3ba6a5e9.
* fix test import after curves have a new version
* chore: Release ark-r1cs-std version 0.4.0-alpha.3

* 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.

* 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)
