- Read in Excel files following the specification.

# Important Notes
- Minor fix to DelimitedReader for Windows
Implements https://www.pivotaltracker.com/story/show/181266184
### Important Notes
Changed example image download to only proceed if the file did not exist before - thus cutting on the build time (the build used to download it _every_ time - which completely failed the build if network is down). A redownload can be forced by performing a fresh repository checkout.
- Added Encoding type
- Added `Text.bytes`, `Text.from_bytes` with Encoding support
- Renamed `File.read` to `File.read_text`
- Renamed `File.write` to `File.write_text`
- Added Encoding support to `File.read_text` and `File.write_text`
- Added warnings to invalid encodings
Implements https://www.pivotaltracker.com/story/show/181805693 and finishes the basic set of features of the Aggregate component.
Still not all aggregations are supported everywhere, because for example SQLite has quite limited support for aggregations. Currently the workaround is to bring the table into memory (if possible) and perform the computation locally. Later on, we may add more complex generator features to emulate the missing aggregations with complex sub-queries.
- Make it easier to understand the computations.
- Fix issue with First.
- Improve quote handling in Concatenate
- Added validation and warnings to input
Implementation of the Text take and drop APIs
- Added `Range.contains` function
- Added `Text_Sub_Range` type
- Added `Text_Utils.index_of` and `Text_Utils.last_index_of` based on ICU StringSearcher
