Added support to write timestamps with timezones for CSV

[jorgecarleitao]

• Fixed error in converting time64 to string
• Made default options equal the formatting used by chrono (so, rfc3339)
• Added support to write timestamps with timezones (both +XX:YY and IANA if chrono-tz is enabled)

backward incompatible migration

Use the options

SerializeOptions {
      date32_format: Some("%F".to_string()),
      date64_format: Some("%F".to_string()),
      time32_format: Some("%T".to_string()),
      time64_format: Some("%T".to_string()),
      timestamp_format: Some("%FT%H:%M:%S.%9f".to_string()),
}

to recover the original behavior
