Refactor param binaries

[DrPeterVanNostrand]

Changes

• Use rust-fil-logger everywhere.
• Changes CLI library from clap to structopt.
• Use "humanized" sector sizes in user prompts.
• Change all user prompts from filecoin_proofs::param::choose_from() to dialoguer::{MultiSelect, Select}.

Commit 7758886 (fakeipfsadd)

• Change CLI library.

Commit e1bd75b (paramcache)

• Renames CLI argument from --params-for-sector-sizes to --sector-sizes
• Manually implements Clone for circuits: StackedCircuit, SDR Proof, FallbackPoStCircuit, FallbackPoSt Sector
• Manually implementing Clone is required because we can't reliably #[derive(Clone)] on generic structs having PhantomData fields.
• Clone-ing circuits makes it so that we don't need to call ::blank_circuit() every time we need a circuit instance.

Commit 4627bd1 (paramfetch)

• Renames CLI argument from --params-for-sector-sizes to --sector-sizes
• Changed ipget to latest version (v0.4.0 to 0.6.0).
• Renamed test file from fil-proofs-param/tests/paramfetch/prompts_to_fetch.rs to fil-proofs-param/tests/paramfetch/mod.rs.

Commit bfb3811 (parampublish)

• Rename CLI argument from --all to --list-all (used for listing all parameter files in the cache dir).
• Add FileInfo struct to store a each parameter's: filename, param-id, file extension, and parameter version (so those strings do not have to be repeatedly derived, also makes filtering and sorting easier).
• Add function is_well_formed_filename() to ensure that a parameter filename are in the expected format.

Commit e913a9a

• Remove filecoin_proofs::param::{choose, choose_from} in favor of dialoguer::{MultiSelect, Select}.

Looks good

Nice, thank you guys for reading through it. If no one has an objection, I am going to rebase this into a single commit before merging (cc. @cryptonemo @dignifiedquire)

Manually, or using the 'squash and merge'? I recommend the latter.

I was going to do a manual rebase, but it doesn't matter. I'll squash and merge.
