Noah 981b2b98e0 Refactor Render Texture-Cache Interface
Since SDL2 is using in-memory bitmaps the same as Canvas engine, the
function names of the render.Engine interface have been cleaned up:

* NewTexture(filename, image) -> StoreTexture(name, image)
  Create a new cached texture with a given name.
* NewBitmap(filename) -> LoadTexture(name)
  Recall a stored texture with a given name.
* level.Chunk.ToBitmap uses simpler names for the textures instead of
  userdir.CacheFilename file-like paths.

Noah 4ad32c6edf SDL2: Cache Bitmaps in Memory, Not on Disk
* Update the SDL2 engine's texture caching to use an sdl.RWops file
  buffer in memory instead of outputting bitmap images to the
  filesystem.

Noah 5893daba58 WASM Texture Caching
* Refactor texture caching in render.Engine:
  * New interface method: NewTexture(filename string, image.Image)
  * WASM immediately encodes the image to PNG and generates a JavaScript
    `Image()` object to load it with a data URI and keep it in memory.
  * SDL2 saves the bitmap to disk as it did before.
  * WASM: deprecate the sessionStorage for holding image data. Session
    storage methods panic if called. The image data is directly kept in
    Go memory as a js.Value holding an Image().
* Shared Memory workaround: the level.Chunk.ToBitmap() function is where
  chunk textures get cached, but it had no access to the render.Engine
  used in the game. The `pkg/shmem` package holds global pointers to
  common structures like the CurrentRenderEngine as a work-around.
  * Also shmem.Flash() so Doodle can make its d.Flash() function
    globally available, any sub-package can now flash text to the screen
    regardless of source code location.
  * JavaScript API for Doodads now has a global Flash() function
    available.
* WASM: Handle window resize so Doodle can recompute its dimensions
  instead of scaling/shrinking the view.

Noah cddc41465f Code Layout Refactor
* All private Doodle source code into the pkg/ folder.
* Potentially public code into the lib/ folder.
* Centralize the logger into a subpackage.
