Writing CSV files With Column Widths Greater Than 255 Characters to Blob Storage

[snestler]

Trying to write a .csv file to blob with the storage_write_csv() function, when one or more columns had >255 characters causes RStudio to crash.

In digging through the internal code of storage_write_csv() I discovered that there are two versions of it -- storage_write_csv_base() and storage_write_csv_readr(). The first function causes the write to fail and RStudio to crash. However, if the readr package in installed and loaded, it will use the second function, which doesn't have an issue with the wide columns.

Might be worth documenting that somewhere. Thanks!
