Snapshot will re-appear in iris-examples eventually

- Removing admitted prophecy spec and making prophecy-related examples (coin-flip and atomic-pair-snapshot) work with the new prophecy support in heap_lang
- Adjusting heap_lang tactics for automation of substitution, closedness, etc. to support prophecy syntax
- Adding notation for prophecy syntax

- Added my version of increment.v for practicing working with logically atomic triples
- Added implementation of coin-flip spec from Turon et al. (POPL'13) with an assumed spec for prophecy variables

make atomic_acc typeclasses-opaque

Use telescopes for atomic accessors, updates and triples; improve mask handling; add notation for all of them

This restricts CAS to only be able to compare literals with literals, NONEV with NONEV and NONEV with SOMEV for a literal.

Show that atomic_step is an AccElim so we can open invariants; get entirely rid of the Em ⊆ Eo side-condition

New atomic updates: defined as a fixed point with existential quantifier; intro lemma using class of Laterable assertions

`sed -i 's/frag_auth_op/frac_auth_frag_op/g' $(find -name "*.v")`

New IntoAcc typeclass to decouple creating and elliminating accessors; ElimInv supports both with and without Hclose
