v0.2.0

#165 should've really been multiple independent pull requests.

Summary:

• update to BinningAnalysis 0.6
• Lattices got reworked to a similar structure as LatticePhysics.jl.
  • unit cell information is now present
  • loading and saving is faster and simpler
  • lattice_iterator_cache moved to the lattice in a mutable form (Dict). This makes it easy to adjust/add new cached objects, but requires type annotations to be fast
  • lattice indices have switched to have fast Bravais indices and slow unit cell indices. This is useful for some lattice iterators
• Measurement optimizations/changes
  • fix prefactors in time integration
  • added a flavor iterator to take those sums out of kernels when possible. (Flavors are a slow index in the greens matrix)
  • added specialization for different greens function types
  • more performance annotations (inbounds, fastmath, inline, propagate_inbounds, simd)
  • added EachBondPairByDistance to speed up current current susceptibilities (which now beat pairing susceptibilities)
  • added a restructuring procedure that maps G[src, trg] to G[src, dir]
• Created MonteCarloAnylsis.jl and moved a bunch of the postprocessing/analysis stuff over there. This should make MonteCarlo.jl a bit lighter on dependencies.
• Improved performance of file io
• Some general cleanup/improvements/tweaks

v0.1.0

#165 will have a bunch of breaking changes, many of which aren't backwards compatible. This means that loading old files will likely not work after that pr is merged. To make it a bit easier to deal with this I decided to tag a version now, so that one can jump back to it when needed.
