default values for floats/doubles are not rendered

Example

Schema

{
  "definitions": {
    "Data": {
      "type": "object",
      "properties": {
        "frequency": {
          "type": "number",
          "default": 0.1
        },
        "amount": {
          "type": "integer",
          "default": 42
        },
        "reason": {
          "type": "string",
          "default": "I'm a teapot"
        }
      }
    }
  }
}

Invocation

$ cargo typify --no-builder example.json

Expected

frequency is expected to not be optional and use a default function like reason.

Meta

$ cargo typify --version
cargo-typify 0.0.14

Real version is: c9d6453fc3cf69726d539925b838b267f886cb53 (main)

Reproduce the issue with the shown JSON Schema and cargo typify --no-builder example.json, then inspect how numeric defaults are rendered in the generated Rust. Done means frequency is non-optional and uses a default function like reason, while the existing integer and string defaults remain correct.
