**Major update**
**Should be considered incompatible with prior releases due to function/variable name changes.**
- Better PEP8 compliance. Prior versions used mixedCase for functions and variables that directly correlated with I/O module procedures. Those have now been "translated" to snake_case and future added functionality should follow suit.
- Added var_attributes to header class
- Added var_sets to header class (potentially unreliable when writing - details in source)
- Added low/high values for use in missing ranges (these return -inf and inf when reading metadata)
- Time formats (TIME, DTIME, MTIME) are now converted to/from timedelta objects instead of datetime objects
- WKDAY and MONTH formats are no longer treated as datetime objects
- Dataframe default index now reflects row_offset. For example, instead of `RangeIndex(0, row_limit)`, the returned index is now essentially `RangeIndex(row_offset, row_offset + row_limit)` to match the actual rows that were read.
- When reading strings, only trailing spaces are stripped instead of all whitespace characters.
- Added SPSSError and SPSSWarning classes for special handling (warnings might be too verbose, so added show_warnings setting to config with default value = False)
