[FL-3884] Proper integer parsing (#3839)
* feat: strint_to_uint32 and tests * fix: permit explicit bases and prefixes * feat: strint_to_{int32,uint16,int16} * feat: strint_to_u?int64 * refactor: replace strtol, strtoul, sscanf with strint_to_* * fix: api symbols * docs: document parameter `end` of strint_to_uint_32 * style: apply changes requested by hedger * refactor: fix pvs-studio diagnostic * style: apply changes requested by CookiePLMonster * fix: unused var * fix: pointer type * refactor: convert atoi to strint_to_* * fix: strint_to_uint8 doesn't actually exist ._ . * fix: memory leak * style: address review comments * Toolbox: couple small comments in the code and doxygen comment update. SubGhz, Loader: fix strint usage. * Loader: fix incorrect cast Co-authored-by: あく <alleteam@gmail.com>

* - If it starts with a `0`, it's read in base 8;
