Reset CURRENT_SIZE to Size::Word before parsing a data directive
...
Previously, the following program:
push.16 0
data.16 0
... crashed fox32asm:
thread 'main' panicked at 'internal error: entered unreachable code', src/main.rs:620:22
stack backtrace:
0: rust_begin_unwind
at /usr/src/rustc-1.63.0/library/std/src/panicking.rs:584:5

4: fox32asm::build_ast_from_expression
5: fox32asm::main
note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
The issue in line 620 is that parse_data expects a constant in the form
of AstNode::Immediate32, but finds an AstNode::Immediate16, because
CURRENT_SIZE was previously set to Half. Set CURRENT_SIZE to Word when
starting to parse a new data directive, in order to fix this issue.
