feat: implement write syscall in engine (#20) (#109)

This commit adds support for the `write` syscall to symbolic execution and rarity simulation. It also changes how invalid addresses passed to `read` and `write` are handled by reporting them as bugs now.

# [0.3.0](v0.2.0...v0.3.0) (2021-03-10)

### Bug Fixes

* ordering for harmonic mean (less is always better) ([#114](#114)) ([8ae2be8](8ae2be8))
* **rarity:** use right amount of values for mean calculation ([#114](#114)) ([c365767](c365767))
* broken build due to wrong Selfie repo URL ([883821b](883821b))
* enforce unique input variable names for Z3/Boolector ([#111](#111)) ([a0ed9d4](a0ed9d4))
* swapped handling of --iterations and --selection ([#113](#113)) ([c05c743](c05c743))
* **rarity:** Add warning message to ignored partial read ([43e8297](43e8297))
* **rarity:** detect REMU with 0 remainder as bug ([8e989cb](8e989cb))
* **rarity:** Fix filtering before enumerating skewing scoring counter index ([6e99b15](6e99b15))
* **rarity:** Fix rarity scoring ([ba7d0ed](ba7d0ed))
* **rarity:** implemented score algorithm exactly as in the paper ([afe4e9d](afe4e9d))
* **rarity:** push the raw input values only ([d6448bb](d6448bb))
* **rarity:** update dependencies to be compatible with Selfie ([0e86d8d](0e86d8d))
* **rarity:** Use correct format string flag for Format trait ([13cd96c](13cd96c))
* **rarity:** Use f64 for rarity score instead of u64 ([bd363e1](bd363e1))

### Features

* add coin-flip execution path exploration strategy ([081ec28](081ec28))
* create api for rarity simulation ([10aded4](10aded4))
* implement write syscall in engine ([#20](#20)) ([#109](#109)) ([d2fffde](d2fffde))
* **rarity:** adapt engine file for rarity simulation ([aa39116](aa39116))
* **rarity:** add benchmarks as submodule ([d4cb2be](d4cb2be))
* **rarity:** Add bytewise state comparator ([ef72317](ef72317))
* **rarity:** Add CLI parser config for rarity simulation ([7b9e001](7b9e001))
* **rarity:** CLI option to switch between harmonic and arithmetic mean ([90c4174](90c4174))
* **rarity:** detect bugs during concrete execution ([01ace2a](01ace2a))
* **rarity:** Implement copy-create ratio for newly created states ([00e3f10](00e3f10))
* **rarity:** implement search algorithm (breadth-first) ([09e5d64](09e5d64))
* **rarity:** Use harmonic mean as metric ([f30f41e](f30f41e))

* **smt:** zero extend bitvectors for comp ops in external solver ([2576441](2576441))
* **test:** syntax errors in C* examples ([dc60453](dc60453))

### Features

* **symbolic:** add support for openat system call ([#20](#20)) ([de71a0c](de71a0c))
* create custom CLI command for SMT-lib file generation ([2e8eb46](2e8eb46))
* handle exit points with unknown satisfiability ([8891c64](8891c64))

### Performance Improvements

* switch rarity simulation to segmented memory ([7d31865](7d31865))
