Rewrite static filtering parser
This commit is a rewrite of the static filtering parser into a
tree-based data structure, for easier maintenance and better
abstraction of parsed filters.

This simplifies greatly syntax coloring of filters and also
simplify extending filter syntax.

The minimum version of Chromium-based browsers has been raised
to version 73 because of usage of String.matchAll().

Group all compiling-related code into FilterCompiler() class
In the static network filtering engine (snfe), the
compiling-related code was spread across two classes.
This commit makes it so that all the compiling-related
code is in FilterCompiler class, which clear purpose is
to compile raw filters into a form which can be persisted
and later fed to the snfe with no parsing overhead.

To compile raw static network filter, the new approach is:

    snfe.createCompiler(parser);

Then for each single raw filter to compile:

    compiler.compile(parser, writer);

The caller is responsible to keep a reference to the
compiler instance for as long as it is needed. This removes
the need for the clunky code used to keep an instance of
compiler alive in the snfe.

Additionally, snfe.tokenHistograms() has been moved to
benchmarks.js, as it has no dependency on the snfe, it's
just a utility function.

Move orphanizeString() into text-utils module
Another small step toward the goal of reducing dependency
on `µb`.

text-iterators module has been renamed text-utils to better
reflect its content.

Modularize codebase with export/import
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1664

The changes are enough to fulfill the related issue.

A new platform has been added in order to allow for building
a NodeJS package. From the root of the project:

    ./tools/make-nodejs

This will create new uBlock0.nodejs directory in the
./dist/build directory, which is a valid NodeJS package.

From the root of the package, you can try:

    node test

This will instantiate a static network filtering engine,
populated by easylist and easyprivacy, which can be used
to match network requests by filling the appropriate
filtering context object.

The test.js file contains code which is typical example
of usage of the package.

Limitations: the NodeJS package can't execute the WASM
versions of the code since the WASM module requires the
use of fetch(), which is not available in NodeJS.

This is a first pass at modularizing the codebase, and
while at it a number of opportunistic small rewrites
have also been made.

This commit requires the minimum supported version for
Chromium and Firefox be raised to 61 and 60 respectively.
