Static regexes

[bendikberg]

Purpose

Dynamo uses a lot of regexes in many places, many of which can be made static, since the regex pattern never changes. This PR changes most of the regexes I could find where the pattern never changes to a static compiled regex.

Adding the Compiled option to the Regex creation flags increases construction time a little, but creates a faster regex.

There is a fairly recent C# feature for compiling regex into the .dll using attributes. I did not want to move regexes around or change classes to be partial, so I avoided this. Using that feature would probably lead to bigger performance gains.

Performance

Example gain:

Code block instantiation (old)

Code block instantiation (new)

Every function that uses regex and gets called multiple times in quick succession (probably) gains a fair amount of speed from this, as the regex construction and compilation is avoided. See for example the unit or PII methods, which I would imagine are called fairly often in actual Dynamo use, and which use large and complicated regex expressions.
