Cannot write a parquet file having a comma in one of its headers

[bartero]

I came across a very unfortunate problem using this library.
Whenever I try to read a parquet file created with this same tool and containing a comma , in any of its headers.
I get this error while await parquetReader.getCursor().next(): TypeError: Cannot read property 'fields' of undefined
stacktrace:

at ParquetSchema.findField (../../.yarn/cache/parquetjs-npm-0.11.2-9df3a54481-63137e17bc.zip/node_modules/parquetjs/lib/schema.js:35:22)
      at Object.exports.materializeRecords (../../.yarn/cache/parquetjs-npm-0.11.2-9df3a54481-63137e17bc.zip/node_modules/parquetjs/lib/shred.js:164:26)
      at ParquetCursor.next (../../.yarn/cache/parquetjs-npm-0.11.2-9df3a54481-63137e17bc.zip/node_modules/parquetjs/lib/reader.js:62:40)

I guess this is caused by a rather "unsafe" operation in the parquetjs/lib/schema.js file on line 28: path.split(",")

I would be very helpful for any help with this problem.
Thank you!
