2.0.0-alpha

• rewrite the whole program in rust
• remove --latest flag, it's the default behavior now
• remove --dry-run flag, but you can enable the feature debug and build to get the same result
• remove --locale flag since there are no other server anymore 😢
• remove --checksum flag temporarily, but will add it back after I implement it
• rename --output-path to --output
• rename -b, --batch-size to -P, --parallel

The macOS binaries are cross compiled from linux and aren't tested yet.
