Release version 0.3.0

[cgrdn]

There are several to-do's/issues that once resolve, would warrant the release of a major version update. This issue will track their status:

• Argo netCDF file writing, output file must pass Argo FileChecker (Writing adjusted variables and flags #11)
• Retrieving gridded (2D array) variables from an Sprof file, rather than only 1D vectors (Should be able to get gridded variables as in sprof files #16)
• Exhaustive formatting and docstrings (General Formatting #28, which was merged into Package is expanding - re-organize #39)
• Dealing with missing PPOX_DOXY variable in traj files for calculating in-air gain (Calculating in-air gain when there is DOXY variable in traj file without PPOX_DOXY #29)
• Calculating gain including the carry-over factor (Gain with carry-over calculation #33)
• The package has grown and 1000+ line files are impractical, re-organize into folders with more files and __init__.py files (Package is expanding - re-organize #39)
• Retrieve optode type before calculating oxygen solubility (Check optode type for solubility calculation #40)
