v1.0.0

V1 is a major rewrite of UnitMath in TypeScript. While most of the API remains the same, V1 does introduce several breaking changes from v0.8.7. See Migrating to v1 for details.

• toString no longer simplifies units. You must now explicitly call simplify for the unit to be simplified.
• Removed simplify and simplifyThreshold options.
• Removed definitions.quantities and definitions.baseQuantities.
• Renaned definitions.unitSystems to definitions.systems
• Renamed definitions.prefixes to definitions.prefixGroups
• Each system defined in definitions.systems is now just a string array of units assigned to that system.
• Removed autoAddToSystem option, since it is now much easier to add units to a system.
• Customer formatters no longer accept additional user arguments.
