Add additional ISQ derived quantities

[gdtroszak]

Track additional ISQ quantities to add to dim-isq. These are commonly used derived quantities from ISO 80000 that are not yet in the package.

Quantities sharing a dimension with an existing quantity are marked as alias — they produce a structurally identical type but provide a distinct name for readability and intent. See the Limitations section in the README.

Each item follows the adding a new ISQ quantity checklist.

• density — M·L⁻³
• specificVolume — M⁻¹·L³
• momentum — M·L·T⁻¹
• angularVelocity — T⁻¹ (alias: same dimension as frequency)
