Update vendored equations-parser code (fe93ca5 .. ec64e60)

[rodiguif]

What this is

Updates the vendored equations-parser code in core/src/main/cpp/parser, which had been stuck since commit fe93ca5 (Nov/2022), up to the current HEAD ec64e60.

Instead of copying files one by one, this was done with a 3-way merge (git merge-file, BASE = fe93ca5, LOCAL = Android customizations, UPSTREAM = ec64e60), which applies upstream changes on top of the local customizations automatically.

(Other commits from that period — 7428a00, e7650c1, a210f5d, a4606cd, fea0e4d, ecf9a64, af58a4c — only touched the equations-parser README, CMake config, or tests/CI, outside the vendored parser/ folder, so they have no effect here.)

How the result was validated

Every new feature above was checked individually (class declared + defined + registered via DefineFun), and every small removal/tweak (e.g. removing std::binary_function, simplifying a ternary, the GCC 11.3 fix, removing debug logs) was confirmed present in the final result.

Final comparison between equations-parser/parser (HEAD) and this module's core/src/main/cpp/parser (run from the parent directory containing both repos as siblings):

The only remaining differences are pre-existing Android-side formatting quirks (a stray blank line, a missing space before {, indentation inside an #ifndef block) — confirmed identical to their state before this sync, unrelated to any change in this PR. No functional/content difference. Every other file in parser/ ended up byte-for-byte identical to upstream.

Notes

• equationsParser.cpp/h (new upstream since bfd3d5a) was ported — it's a real dependency of the calculate(s) function added in 39d949b, not just optional convenience code (the build failed to link without it: undefined symbol: EquationsParser::Calc).
• Tested locally by building the core module (Debug, arm64-v8a and x86) via Android Studio.
