Calkulate - Calkulate: total alkalinity from titration data in Python

Changes in v23.5

• Added to_pandas method to Dataset for a more convenient downgrade to a pandas DataFrame.
• Improved docstrings for several key functions and classes.
• Fixed bugs in logicals in various calk.dataset functions which had meant that NaN values in the metadata file were not always being ignored.
• Fixed bug in the Dataset.solve method such that the analyte_mass is now automatically calculated from analyte_volume.
• Switched to using pyproject.toml instead of setup.py for building the package.
• Renamed module io as read.

Changes in v23.1.0

• Add solvers for titrations with an H2SO4 titrant (see optional titrant column in the metadata contents).
• Added optional titrant_density column to overwrite the internally calculated titrant density with a user-specified value.

Changes in v23.0.1

• Print more informative error messages when titration data files cannot be found.
• Use read_dat_genfromtxt by default if read_dat_method not recognised, instead of throwing an error.

Changes in v3.1.0

Major bug fix

• Fixed unit conversion bug when evaluating equilibrium constants in PyCO2SYS. All results calculated using v3.0.X should be redetermined!

Better consistency with PyCO2SYS

• Updated for compatability with PyCO2SYS v1.6.0.
• Added two optional extra alkalinity components.
• Renamed various internal variables for better consistency.

Changes in v3.0.1:

Bug fixes

• Fix bug in handling data["file_good"] = False cases.
• Set DIC to zero where its value is NaN.
• Skip over errors in titration files with a warning rather than throw a breaking error.

Calkulate - Introducing the `Potentiometric` titration object

• Added convert module with convenience functions to convert acid and sample volumes into masses.
• Relocated EMF to [H+] conversion functions from solve to convert, with aliases to maintain backwards compatibility.
• Added titration module with new Potentiometric class for higher-level manipulation of titration datasets.
• Added plotting functions for Potentiometric titration objects into the plot module.

Calkulate - Integrated with PyCO2SYS

• Updated concentrations.concTotals and dissociation.eqConstants to use PyCO2SYS functions to calculate things instead of functions built in to Calkulate.
• Removed all equilibrium constant and concentration functions that were previously internally in Calkulate.
• Added optional total ammonia and hydrogen sulfide concentration inputs. If values are provided, these equilibria will now be taken into account by the complete solver.
• Fixed io.writeDat function to correctly delimit .dat files with tabs (not spaces).
• Added simulate.titration function to directly simulate a titration dataset.
• Updated solver functions to optionally accept concTotals['C'] as an array.
• Renamed module vindta to datfile, but added alias to avoid breaking existing code.
