Picoware - v1.7.0

This update to the MicroPython version adds JPEG parsing, a speed boost to the `Python Editor`, dictionary loading support in the `Keyboard` class's `auto complete`, and a new `CCTV` app to watch live streams on the go!

Full details:

Updated:
- `AutoComplete` library with dictionary loading support
- `Keyboard` class to load a dictionary into auto complete if available (stored in `picoware/keyboard/dictionary.txt` with each word/phrase separated by a newline)
- `FlipSocial` with corrected text width, admin parsing, and further optimizations
- `ViewManager` to save the current version of Picoware to `picoware/version.txt` and create a `picoware/keyboard` directory on the SD card
- `Draw` class to use the new `lcd` C module
- `image_bytearray` method of the `Draw` class to handle 8-bit and 16-bit images
- `FileBrowser` to render JPG/BMP files and only show txt, log, cfg, json, py, md, bas, lua, html, css, and js files
- `Python Editor` to use the new `vt` C module (major speed boost)

Added:
- `lcd` C module with a config header that makes it easy to integrate other devices
- `jpegdec` C library and module with a `JPEG` Python class interface (decodes and draws JPEGs)
- `image_jpeg` and `image_jpeg_buffer` methods to the `Draw` class
- `from_file` method to the `PSRAM` class that loads data from a file into PSRAM memory and returns the size of the loaded data
- `CCTV` app: requires a list of CCTV stream URLs in `picoware/cctv/list.txt` on the SD card
- `vt` C module that renders text with syntax highlighting
