Create a number primitive.

[tacosontitan]

A primitive capable of handling the primitive types of C# would help simplify a lot of golf snippets. This type will be known simply as Number and consumable as N:

N foo = 3.14159f;

Ideally, we should have a file per interface implementation required to support the type:

    public readonly struct Number
        : IComparable,
          IConvertible,
          ISpanFormattable,
          IComparable<Number>,
          IEquatable<Number>,
          IBinaryInteger<Number>,
          IMinMaxValue<Number>,
          ISignedNumber<Number>,
          IUtf8SpanFormattable,
          IBinaryIntegerParseAndFormatInfo<Number>

Then one per native primitive being supported to handle conversions:

• byte
• short
• ushort
• int
• uint
• long
• ulong
• decimal
• float
• double

This will likely be the most verbose primitive type the project will have. As a result, the support for each native primitive is approved to be defined in its own file under a folder named Number which is marked as not a namespace provider, as is typical of all folders in the repo. The naming format should be *Functions where * represents the native type (e.g. ByteFunctions) or similar to ensure functionality can be maintained in bite-sized chunks.
