Describe the bug

PostgresNumeric cannot decode large number (like 1234567890123) and it causes runtime crash.

To Reproduce

1. call this line

PostgresNumeric(string: "1234567890123")

2. crash!

Expected behavior

Can call initializer without crash.

Environment

• Vapor Framework version: 4.48.8
• postgres-nio: 1.6.2

Additional context

this function does not work correctly and return values over maxSize.

let uuu = "1234567890123"
print(uuu.reverseChunked(by: 4)) // ["1", "2345", "67890", "123"]

then here, Int16(67890)! causes crash.
