---------------------------------------

[~Max Risuhin] can you take a look since you last twiddled with the symbol visibility? Extern templates are a beast of their own

> This regression was introduced in https://github.com/apache/parquet-cpp/commit/fc5228af3eee2ec8176e404ecb34b7ba985d0e4d. It can be seen with
> ((fc5228a...))$ nm -g debug/libparquet.so | c++filt | grep parquet::TypedColumnReader
> compared with the prior commit. We need to change one of our examples (like the reader-writer example) to use dynamic linking so this problem is caught in the future.
