Add schema checking for HyVee

[Mr0grog]

In #714, I had to make some changes to HyVee and noticed that the data we get from them is no longer quite the same (it was not different enough to be problematic, but there was drift).

We should add schema checking using assertSchema for the data we get from HyVee, just like we added for Rite Aid in #532 and #547:

univaf/loader/src/sources/riteaid/scraper.js

Lines 132 to 196 in a849fae

	// API data for each location should look like this. The schema is fairly strict
	// since we are pulling on an unversioned API designed for the web UI, and want
	// the system to scream at us for any potentially impactful change.
	const riteAidLocationSchema = {
	type: "object",
	properties: {
	storeNumber: { type: "integer", minimum: 1 },
	brand: { enum: ["RITEAID", "BARTELL", "UNKNOWN", null] },
	customDisplayName: { type: "string", nullable: true },
	address: { type: "string" },
	city: { type: "string" },
	state: { type: "string", pattern: "[A-Z]{2}" },

	},
	fullZipCode: { type: "string", pattern: "\\d{1,5}-\\d{1,4}" },
	fullPhone: { type: "string", nullable: true },
	locationDescription: { type: "string" },

	availableSlots: {
	type: "array",
	items: {
	type: "object",
	properties: {
	date: { type: "string", format: "date" },
	available_slots: { type: "integer", minimum: 0 },
	slots: {
	type: "object",
	patternProperties: {
	"\\d+": {
	type: "array",
	items: {
	type: "object",
	properties: {
	appointmentId: { type: "string", pattern: "\\d+" },
	apptDateTime: { type: "string" },
	},
	required: ["appointmentId", "apptDateTime"],
	additionalProperties: false,
	},
	},
	},
	additionalProperties: false,
	},
	},
	required: ["date", "available_slots", "slots"],
	additionalProperties: false,
	},
	},
	},
	additionalProperties: false,
	};
	riteAidLocationSchema.required = Object.keys(riteAidLocationSchema.properties);
	function formatLocation(apiData) {
	assertSchema(riteAidLocationSchema, apiData);
