Emi float64 data type

Example schema:

name: MyFloatClass
fields:
  - name: floatWithDefault
    default: 3.14
    type: float64
  - name: plainFloat
    type: float64

• float64 maps to JavaScript number with double precision.
• Default is 0.0 if not specified.
• float64? allows null and undefined, defaulting to undefined.

Nullable version:

name: MyFloatClass
fields:
  - name: nullableFloatWithDefault
    default: 1.23
    type: float64?
  - name: nullableFloatWithoutDefault
    type: float64?

Defaults to undefined, but you can assign any float value or null.
