Update roadmap

The column types were tracked just as a Type. This changes them to be an instance
so they can track additional information (such as the specific units of a physical
units type). Because of this, the column type attribute need to be passed as strings
(see CS0181).

 ## Roadmap
 
 - Improve error reporting by including line/column information in exceptions
-- Come up with a static-typing interface
+  - Use this to get line numbers for parallel parsing implementations
+- [x] Come up with a static-typing interface
+
   Something that doesn't require an array of objects
+
+  Use a class with SaveTsv attributes
+
 - Check numeric formatting matches spec
-- Do parallel parsing / serializing implementation
+- [x] Maybe add a binary representation for f32/f64. It should specify that it is Little-endian (since we have to pick one). That way we can guarantee bit-compatibility between implementations where an application might require that.
-  - Next task: Refactor parsing so that it will start and end at arbitrary indices and return an array of SaneTsvRecords. The refactor should ignore the current record (unless at the start of the buffer) and continue parsing the record the end index is in.
+- [x] Add Column name/type specification to API
-- More optimization and making parsing modular:
+  - So you can tell it what columns to expect
+  - [ ] Lax/strict versions
+  
+  See the attributes thing above
+- Generate test cases
+  - [x] File comment / no file comment
+  - [x] header types / no header types
+  - [x] Line comments / no line comments
+  - [x] end of file comment
+  - [x] Test with the start index of parallel methods in last record
+    - end index in first record
+  - [x] Extra \n at end of file
+  - [x] Wrong number of fields
+    - Wrong number of fields at end of file
+

+  - [x] Next task: Refactor parsing so that it will start and end at arbitrary indices and return an array of SaneTsvRecords. The refactor should ignore the current record (unless at the start of the buffer) and continue parsing the record the end index is in.
+- ~~More optimization and making parsing modular:~~
   - Have callbacks for header parsing and field parsing
   - That way other formats (like ExtraTSV) don't have to iterate through the entire set of data again.
-- Finish ExtraTSV implementation
+- [x] Make untyped Simple TSV (De)serialization
-- Do zig implementation
+- [x] ~~Finish~~ Minimal ExtraTSV implementation
+- [ ] Do zig implementation
 - Make a c interface from that
+- Make a commandline interface
+- Make a viewer / editor
+- Streaming interface
+  So you can start processing your data while it finishes parsing?
+- [ ] Decoding a binary stream with a \0 in it via UTF-8 doesn't seem to cause any issues. I thought that valid UTF-8 wouldn't have a \0?
+- [ ] Instead of exceptions when parsing, we should parse as much as possible and reflect parsing errors in the returned data structure
