Subject: [PATCH] fix: Add miniz directive to get rid of compilation warning
 (#858)

## Summary

* I am getting miniz warning during compilation: "Using fopen, ftello,
fseeko, stat() etc. path for file I/O - this path may not support large
files."
* Disable the io module from miniz as it is not used and get rid of the
warning

## Additional Context

* the ZipFile.cpp implementation only uses tinfl_decompressor,
tinfl_init(), and tinfl_decompress() (low-level API) and does all ZIP
file parsing manually using SD card file I/O
* it never uses miniz's high-level file functions like
mz_zip_reader_init_file()
* so we can disable Miniz io-stack be setting MINIZ_NO_STDIO to 1
