Jack Grigg e36041d198 halo2_gadgets 0.1.0 
Closes zcash/halo2#460.

Jack Grigg 342ebdd15e halo2_gadgets: Fix return type of `ecc::chip::FixedPoint::u` 
This trait method was previously preventing the trait to working with
fields that encode to more than 256 bits.

Jack Grigg 3486703bd2 halo2_gadgets: Refactor fixed-base scalar mul gadget APIs 
The new `EccInstructions` instructions, and the corresponding changes to
existing instructions, enable chips to choose when to witness or constrain
the scalars, and simplify scalar reuse (though reuse is not implemented
for `EccChip` yet).

`FixedPoint::mul` and `FixedPointShort::mul` now has the same API style
as `NonIdentityPoint::mul`.
