emoji: provide options for each position 
Per https://github.com/vbatts/emojisum/issues/5 there are some options
in this list that are better expressed as a unicode codepoint.

Abstract

This document specifies a practice of mapping an 8bit byte to one of a corresponding list of 256 emoji strings.

The emojimap.json JSON is the authority of ordering. While this directory contains golang source that is is importable by golang projects, other languages can fetch the ordered list of the JSON document and do their own emojisum comparison or rendering.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

Introduction

Purpose

The purpose of this practice is provide simplified way to convey checksums for visual comparison.

Intended Audience

This is intended for use by implementors of software to convey checksums or validate conveyed checksums.

Details

By operating on an 8bit byte, this provides the oportunity for 256 permutations. Most checksums convey in a hexadecimal notation, there showing a par of case-insensitive hexadecimal characters per byte (16*16 = 256). Having a mapping of 256 emojis this thereby reduces the number of characters (or emojis) needed to convey the checksum. In example, a SHA1 checksum is 40 hexadecimal characters long, whereas an SHA1-emojisum is only 20 emojis.
