feat: update from manifest initializer

[brpowell]

What does this PR do?

Updates the signature for the manifest initializer with the following:

• Supports passing in a single path to a manifest file
• Supports passing in an options object to specify behavior of the initialization

Refactors some functionality:

• Moves component resolution for manifests to a ManifestResolver class to mirror the one we have for resolving source (should be renamed to SourceResovler perhaps). This cleans and simplifies the ComponentSet class a bit more.

Breaks some stuff:

• Renamed to ComponentSet.fromManifest()
• Renamed resolve option to resolveSourcePaths
• Renamed literalWildcard option to forceAddWildcards

Adds better documentation:

• Adds more robust docstring for fromManifest
• Adds docstrings for options to elaborate on usage.

What issues does this PR fix or reference?

Functionality Before

const set = ComponentSet.fromManifestFile('/project/package.xml', {
  resolve: ['/project/force-app'],
  literalWildcard: true
})

Functionality After

// single path with default options
const set = ComponentSet.fromManifest('/project/package.xml')

// or options object
const set = ComponentSet.fromManifest({
  manifestPath: '/project/package.xml',
  resolveSourcePaths: ['/project/force-app', '/project/test-app'],
  forceAddWildcards: true
})

Is resolvePaths referring to resolveSourcePaths?

[brpowell]

indeed it is, good catch

Minor doc updates - rest looks good.
