2c3be946ec Keep type positions on the right-hand side upon unification of types
This should result in more predictable error messages. Right-hand is arbitrary,
but has been found empirically to give better results.

Use dates_calc library (#306)
This is a WIP. Current version 0.0.2 of `dates_calc` is in the process of being published, so I guess the CI should fail currently.

- [x] Test current implementation
- [x] I commented out the `duration / duration` operator, can we remove it?
- [x] Need to add support for first and last day of month
- [x] Finish porting the Z3 backend to dates_calc

Louis Gesbert
54eee2edea Rationalise the tuple / enum types
This will allow to unify with types used earlier in the
pipeline (`Scopelang.Ast.typ`).

It seems cleaner! But some areas may warrant a later clean-up, in particular
handling of options and their types in the backends, or possible name conflicts
of structs/enums with built-in types when printing.

576e0fb3ff Factorise AST printers
Note that there were significant differences between the two printers (see the test diff!). Overall the `dcalc` one seemed newer so that's what I took, with only the required additions from `lcalc` (exceptions, raise and catch)

ae2801be6d Move mode handling code from dcalc to shared_ast
Handling code should now be reasonably well sorted between `Shared_ast.{Var,Expr,Scope,Program}`

The function parameters (e.g. `make_let_in`) could be removed from the
scope handling functions since now the types are compatible, which
makes them much easier to read.

b5579cde3d Generalise the expressions between dcalc and lcalc
The huge benefit of this approach is that almost no changes are needed and we get compatible types between dcalc and lcalc, allowing to deduplicate a few functions.

It might not be the best in the long run: there are still benefits in factorising small parts of the AST as suggested in #157, and this forces a central AST definition that makes the nanopass-like approach a bit less legible.

Still, I think it's a step in the right direction and it doesn't really lock us in keeping to use the big GADT (as the minimal cascade of changes show).

513647cd32 AST simplification: remove redundant annotations
The AST structures track annotations (e.g., at the moment, source code
position information) in a lot of places. This patch tidies up a bit and
removes some duplication, ensuring a single level of annotation wrapping
at each AST recursion level.

This will be important when adding type information in these
annotations, because there will be consitency constraints to be ensured
and duplication is a likely source of mistakes.

12ec65601d Use format strings directly in debug/error/log functions
This avoids many intermediate calls to e.g. `Format.asprintf`; should result in
some cases in "more correct" use of `Format`¹, avoid the computation of unused
debug strings, and make the code more readable.

¹ for `Format` to work as expected, all intermediate calls need to go through
it. Some cases of formatting to an intermediate string then printing through Format
again are still present, but this makes the situation better.
