Instead of a "human" aimed list of available corners, this generates a
machine readable list of liberty files that can be generated for a
given library.

Instead of giving the library and corner to gnerate, you can provide
the target .lib file you want generated and this will pick the right
parameters to generate that file

Since this script will be used in Makefile to generate machine parseable
output, it's importatnt that all 'user' messages are sent to stderr to
be differentiated from the 'machine' output

This also fixes a bug in liberty_float for numbers with a magnitute
between 9 and 15.
Previously:
>>> liberty_float(1e15)
'1000000000000000'
>>> liberty_float(1e10)
'10000000000.'
>>> liberty_float(1e9)
'1000000000.0'
>>> liberty_float(1e16)
'1.000000e+16'
Now:
>>> liberty_float(1e15)
'1.000000e+15'
>>> liberty_float(1e10)
'1.000000e+10'
>>> liberty_float(1e9)
'1000000000.0'
>>> liberty_float(1e16)
'1.000000e+16'
* Add functions for producing different types of values into liberty
output (plus doctests for them).
* Respect the type given by a `define()` statement.

Fixes#37, #40.
The `LIBERTY_ATTRIBUTE_ORDER` template is used to control the ordering
of the liberty attribute output.

On the flake8 test selection, this PR does _not_ focus on "_style violations_" (the majority of flake8 error codes that [__psf/black__](https://github.com/psf/black) can autocorrect). Instead these tests are focus on runtime safety and correctness:
* E9 tests are about Python syntax errors usually raised because flake8 can not build an Abstract Syntax Tree (AST). Often these issues are a sign of unused code or code that has not been ported to Python 3. These would be compile-time errors in a compiled language but in a dynamic language like Python they result in the script halting/crashing on the user.
* F63 tests are usually about the confusion between identity and equality in Python. Use ==/!= to compare str, bytes, and int literals is the classic case. These are areas where __a == b__ is True but __a is b__ is False (or vice versa). Python >= 3.8 will raise SyntaxWarnings on these instances.
* F7 tests logic errors and syntax errors in type hints
* F82 tests are almost always _undefined names_ which are usually a sign of a typo, missing imports, or code that has not been ported to Python 3. These also would be compile-time errors in a compiled language but in Python a __NameError__ is raised which will halt/crash the script on the user.
