Rename functions according to the terminology RFC (#622, #586, #571, #403, #466, #495, #466)

Cell count parameters use int64_t instead of int.
polygonToCells (previously polyfill) accepts a flags argument for future expansion. (#570)
cellToLocalIj and localIjToCell accept a mode argument for future expansion. (#586)
exactEdgeLength functions renamed to edgeLength (#639)
Fixed
Fix polyfill bug when vertex latitude exactly matches cell center. (#603)
A number of issues detected via unit tests and fuzzers were fixed. (#568, #562, #558, #559, #560, #430)
polygonToCells returns an error if Infinity is passed in. (#636)
Changed
The file CMakeTests.cmake is no longer included if ENABLE_TESTING is off. (#609)
Added
Vertex mode and associated functions: (#422, #420, #417)
cellToVertex(cell, vertexNum)
cellToVertexes(cell, out)
vertexToLatLng(vertex, out)
isValidVertex(vertex)
h3 CLI application. (#556, #497)
Other changes
Generally use lng instead of lon
Closed-form implementation of numHexagons
A number of fuzzer harnesses are now included in the H3 core library. (#557, #553, #545, #433)
Additional benchmarks are added and benchmarks are regularly run in CI. (#524, #518)
