v0.1.5

This release updates the GUI and has the following improvements:

• Cancel for cancelling conversion and collation.
• Pre-conversion tag checking, so undefined behaviour is less likely.
• Visibility of the number of files and tags loaded (shown in search bars).
• Ordering options for collation (Sort by Name; Drag to Rearrange Files).
• Average every 'N' rows to reduce file size and precision.
• Set Decimal Places.
• Progress bar modifications to show Collating when collating.
• A Log to display all output, replacing large error messages.
• Configurable number of CPU cores for parallel conversion.

Pre-conversion tag checking fixes #1.

Other:

• All CSV conversion features and unused threading classes have been removed.
• Collator has been refactored into its own widget to allow functionality extension.

Known Issues:

• The blue colour of the progress bar disappears when loading files or tags (PyQt5 issue with Fusion scheme on Windows)
