##### PackageAssets with Spaces and Quotes Benchmark Results

Similar to the benchmark related to quotes here spaces ` ` and quotes `"` are
added to relevant columns to benchmark impact of trimming and unescape on low
level column access. That is, basically ` " ` is prepended and appended to each
column. This will test the assumed most common case and fast path part of
trimming and unescaping in Sep. Sep is about 10x faster than CsvHelper for this.
Sylvan does not appear to have support automatic trimming and is, therefore, not
