Describe the bug
When calling listEntities(), one of the entities in my table contains a value of "1.23456789012346e+24". This is clearly beyond the limits of an Int32 value, yet Int32 is the type that's returned by the SDK. This happens even if the value is explicitly inserted as a Double.

To Reproduce
Steps to reproduce the behavior:

1. Write the following program:

let client = new TableClient("https://myacct.table.core.windows.net", "mytable", someCred);
const inputEntity = {
    partitionKey: "0",
    rowKey: "0",
    Value: { value: "1.23456789012346e+24", type: "Double" }
};
await client.insertEntity(inputEntity);

let response = client.listEntities();
let next = await response.next();
let entity = next.value;

Expected behavior
I would expect inputEntity to have the same value as entity.

Instead, entity has a value of:

 {
    partitionKey: "0",
    rowKey: "0",
    Value: { value: "1.23456789012346e+24", type: "Int32" }
};

@craxal thanks for reporting this issue. I was able to get a local repro. The problem is that the service is not sending enough metadata to tell this is a double and our check is missing checking if the number is a safe integer or not.

I'm preparing a PR for this fix and will send it out soon
