…#554)

There is a new chained fixup format that uses larger addend size for fixup chains: https://github.com/apple-oss-distributions/dyld/blob/3d26957467bbec4f999a0c27ebe09b6fc186f5cd/include/mach-o/fixup-chains.h#L318.

This PR implements the parsing needed to parse them dynamically and continue to populate the imports. The change still parses older style fixups successfully.

I wrote a test binary to generate a mach-o that contained a `DYLD_CHAINED_IMPORT_ADDEND64` format entry because I couldn't find one in the wild to use as a test. :)

```c
extern int some_external_glob;

// force a massive offset that won't fit in 32 bits
void* trigger = (void*)((unsigned long long)&some_external_glob + 0xFFFFFFFF12345678ULL);

int main() {
    return 0;
}
```
