speedtest1 wasm: add a link in the worker variant which launches the main-thread variant with the selected CLI flags. Append collected stdout/stderr to the main-thread page after execution is finished to avoid having to open the dev tools (which inexplicably slows down wasm execution).

/**
Parses window.location.search-style string into an object
containing key/value pairs of URL arguments (already
urldecoded). The object is created using Object.create(null),
so contains only parsed-out properties and has no prototype
(and thus no inherited properties).
If the str argument is not passed (arguments.length==0) then
window.location.search.substring(1) is used by default. If
neither str is passed in nor window exists then false is returned.
On success it returns an Object containing the key/value pairs
parsed from the string. Keys which have no value are treated
has having the boolean true value.
Pedantic licensing note: this code has appeared in other source
trees, but was originally written by the same person who pasted
it into those trees.
