Use the Double primative for JSON Schema "number" type

[mpotter]

Problem

The JSON Schema stipulates that a "number" type can be an integer, floating point, or exponential notation. Currently, the "number" type is treated the same as an integer when instantiating fromJSONSchema. In those cases, providing a float value of e.g. 2.5 will fail because it can't be converted into a BigInt.

Solution

I changed the primitive to Double for "number" types when creating a schema from JSON.

Change summary:

• Use the Double primative for JSON Schema "number" type

Steps to Verify:

Note: This is the example from the README.

import * as parquet from "@dsnp/parquetjs";

var schema = parquet.ParquetSchema.fromJsonSchema({
  "type": "object",
  "properties": {
    "name": {
      "type": "string"
    },
    "quantity": {
      "type": "integer"
    },
    "price": {
      "type": "number"
    },
    "date": {
      "type": "string",
      "format": "date-time"
    },
    "in_stock": {
      "type": "boolean"
    }
  },
  "required": ["name", "quantity", "price", "date", "in_stock"]
});

var writer = await parquet.ParquetWriter.openFile(schema, 'fruits.parquet');

await writer.appendRow({name: 'apples', quantity: 10, price: 2.5, date: new Date(), in_stock: true});
await writer.appendRow({name: 'oranges', quantity: 10, price: 2.5, date: new Date(), in_stock: true});

await writer.close();

Expected behavior is that the file will be successfully written. Current behavior results in RangeError: The number 2.5 cannot be converted to a BigInt because it is not an integer.

LGTM

should we update the tests, too?

Edit: We have to - CI tests are failing 🙈
