Add Fallible Parsing

[jonathan-g-davis]

High level description

Input parsing functionality for dealing with SPICE kernel inputs contains several instances where malformed binary input may result in a panic. This enhancement will create new function signatures for structured error handling by using appropriate Result as return types instead of panicking.

Requirements

• Modify ANISE to return structured errors instead of panicking
  • Use Result<T, E> where applicable
  • New error types may need to be created

Test plans

• Include regression tests to reproduce error and prevent their reintroduction
• Verify fixes with fuzz testing

Design

• Maintain existing function signatures so as not to introduce breaking changes
• Add new function signatures for fallible versions (e.g. try_parse_file)
