Summary:
Add support for Erlang records, including:
- Parsing record definitions, storing info in environment
- Record index expressions and patterns
- Record creation expression, including initializers
- Record update expressions and patterns
- Record field access expressions
- Pulse models
The key idea is to translate records to tagged tuples (just as Erlang does under the hood), but this requires some bookkeeping to figure out which field maps to which tuple element.

Summary: Add support for tuples, including expressions, pattern matching and pulse models. Tuples are modeled similarly to `Cons` (lists): they have a dynamic type (including the size of the tuple) and elements as fields.

Summary: Add some tests for lists: nil, cons, and some basic pattern matching. We can extend this suite later with more features on lists (e.g. concatenation).

Summary: Add support for the xor operator by reducing `(X xor Y)` to `(X and not Y) or (not X and Y)`. Alternatively, `(X != Y)` could have been used but that might not be safe since SIL models Booleans with integers.

Summary: Previously we just reported NONEXHAUSTIVE_PATTERN_MATCH, which was (1) not correct because not only patterns can cause nonexhaustive behavior, but also guards, and (2) the Erlang runtime reports errors more precisely, indicating whether the nonexhaustive behavior occurs with `if`, `case`, functions or match expressions.

Summary: Add support for *unary minus* and *logical not* in the Erlang translation, both as expression (e.g., `X = -Y`) and pattern (e.g., `case X of -3 -> ...`).

Summary: Add some tests for binary expressions. The idea is that tests come in pairs: in both cases we do the same calculations, one is asserting the good result and one is not, where only the latter should trigger a warning.
