Begin implementing human interface for Hyphae 
This commit implements Display and FromStr for Datum, Operation,
Operand, Instruction, and Program types. Additionally, tests are
added for the new routines. This change was implemented in furtherance
of a command line assembler and disassembler, as well as for the
implementation of a debugger.

Mycelium

Mycelium aims to provide an efficient compiled to intermediate bytecode implementation of R7RS Scheme as well as a virtual machine that will execute such bytecode.

Two major use cases are at the forefront of mind when designing and implementing this project: a POSIX shell interpreter as well as a compiled to bytecode language for running on ESP32 devices.

Current Status

The lexer and parser are implemented. On an X86 machine equipped with 64GB RAM and an AMD Ryzen 7900 CPU this lexer and parser are capable of creating a fully validated abstract syntax tree from approximately 11200 lines of handwritten scheme in about 55 milliseconds on average.

HyphaeVM is mostly implemented. The instruction set is defined and implemented, including extensibility interfaces and the VM layout. Additionally, instruction encoding and decoding are implemented. Garbage collection is implemented (via reference counting). Currently being implemented are datum encoding/decoding and full program encoding/decoding. Yet to be approached are debugging routines, CLI utilities, and concurrency features. However, Documentation has been written on programming with HyphaeVM.

The R7RS-Small Scheme to HyphaeVM compiler is not implemented.

R7RS-Large is not implemented.

The Linux/Mac/Windows runtime and extended compiler is not implemented.

Documentation is not implemented.
