Add "pointer scan"-like feature on README (C++)

[rdbo]

Add a function to resolve pointer scans. Example:

lm_address_t GetPointers(lm_address_t start, std::vector<lm_address_t> offsets) {
    for (auto offset : offsets) {
        start = *(lm_address_t *)(start + offset);
    }

    return start;
}

[rdbo]

Name suggestions: LM_GetPointerMap LM_GetDeepPointer LM_ReadPointerMap LM_ResolvePointerMap LM_DerefPointerMap LM_AccessPointerMap LM_PointerMap LM_UnwrapPointer LM_MapPointer LM_DeepPointer

[rdbo]

Sketch:

lm_void_t *
LM_DeepPointer(lm_address_t base, lm_address_t *offsets, lm_size_t noffsets);

template <typename T>
T *LM_DeepPointer(lm_address_t base, std::vector<lm_address_t> &offsets);

Usage:

int *player_health = LM_DeepPointer<int>(some_addr, { 0xF0, 0xA0, 0xE0 });

TODO: Add LM_DeepPointer example on README, it's very attractive to Cheat Engine users

TODO: Add documentation

Done

The README needs to be changed

First, the C++ Wrapper API should be done: #130
