Full CLI refactor (MDP to support inheritance of propagator results)

Given the plethora of changes introduced in version 1.0.0.beta-1, the CLI must be rewritten.

Prerequisites: #160 (closed) #94 (closed)

In order for the differential correctors to be useful, it must be possible for the MD propagation to be sequential based on a solved "problem", like a full CONOPS simulation.

Example I envision:

sequence = ["apo_inject"]

[prop.apo_inject]
# ...

[prop.target_ecc"]
inherit = "apo_inject"
# ...

Specific features:

• Rewrite organization to match the 1.x organization: spacecraft definition should be separate from the dynamics.
• Targeting
• Propagation until events
• Write tests with YAML and JSON loading (should already be supported by config crate)
• Templating of output files to support Monte Carlo run. Might be useful to use (handlebars)[https://crates.io/crates/handlebars] so that info stored in the template itself can be used. In fact, maybe a metadata section would be relevant here.
• Make everything case sensitive: it's confusing to have some things be case sensitive and others not.
• Initial estimates must be seeded from the covariance (seed and distribution can be specified, if not they must be stored)
• Get rid of sequences and understand them from the data files (by specifying the kind)
• Specify convergence criteria in filters
