Bundle specifications denote a well-defined bundle/exchange format.
    The content of a given specification should not change over time in
    order to ensure that bundles produced by a newer version of Mercurial are
    readable from an older version.

The string currently has the form:

<compression>-<type>[;<parameter0>[;<parameter1>]]

Where <compression> is one of the supported compression formats
    and <type> is (currently) a version string. A ";" can follow the type and
    all text afterwards is interpreted as URI encoded, ";" delimited key=value
    pairs.

If ``strict`` is True (the default) <compression> is required. Otherwise,
    it is optional.

Returns a bundlespec object of (compression, version, parameters).
    Compression will be ``None`` if not in strict mode and a compression isn't
    defined.

An ``InvalidBundleSpecification`` is raised when the specification is
    not syntactically well formed.

An ``UnsupportedBundleSpecification`` is raised when the compression or
    bundle type/version is not recognized.

Note: this function will likely eventually return a more complex data
