feat(schema-compiler): Allow to specify td with granularity in REST API query order section

[KSDaemon]

This PR introduces the ability to specify granularity in the order section of the query and fixes the ordering when same time dimension is requested multiple times (with different granularities).

Imaging you have a query like this:

{
        measures: [
          'BigECommerce.rollingCountYTD',
        ],
        timeDimensions: [{
          dimension: 'BigECommerce.orderDate',
          granularity: 'month',
          dateRange: ['2020-01-01', '2020-12-31'],
        }, {
          dimension: 'BigECommerce.orderDate',
          granularity: 'week',
          dateRange: ['2020-01-01', '2020-12-31'],
        }],
        order: [
          ['BigECommerce.orderDate', 'asc'],
        ],
}

Note the order part.

Before now - the sorting will be done by 1st td with month granularity. But resulting rows still could jump around because week timestamps inside one month are not guaranteed to be ordered. Now column with the lowest granularity (week in the example) will be used for ordering.

Btw, this also works with custom granularities! ;)

To have full control, now you can specify the granularity in the order section like this:

{
        measures: [
          'visitors.count'
        ],
        timeDimensions: [{
          dimension: 'visitors.createdAt',
          granularity: 'week',
          dateRange: ['2020-01-01', '2020-12-31'],
        }, {
          dimension: 'visitors.createdAt',
          granularity: 'month',
          dateRange: ['2020-01-01', '2020-12-31'],
        }, {
          dimension: 'visitors.createdAt',
          dateRange: ['2020-01-01', '2020-12-31'],
        }],
        order: [{ id: 'visitors.createdAt.month', desc: false }],
        timezone: 'America/Los_Angeles'
}

or like this:

{
        measures: [
          'visitors.count'
        ],
        timeDimensions: [{
          dimension: 'visitors.createdAt',
          granularity: 'week',
          dateRange: ['2020-01-01', '2020-12-31'],
        }, {
          dimension: 'visitors.createdAt',
          granularity: 'month',
          dateRange: ['2020-01-01', '2020-12-31'],
        }, {
          dimension: 'visitors.createdAt',
          granularity: 'fiscal_quarter',
          dateRange: ['2020-01-01', '2020-12-31'],
        }, {
          dimension: 'visitors.createdAt',
          dateRange: ['2020-01-01', '2020-12-31'],
        }],
        order: [{ id: 'visitors.createdAt.fiscal_quarter', desc: false }],
        timezone: 'America/Los_Angeles'
}
