e59e0ef83d 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
	   1: core::panicking::panic_fmt
		     at /usr/src/rustc-1.63.0/library/core/src/panicking.rs:142:14
	   2: core::panicking::panic
		     at /usr/src/rustc-1.63.0/library/core/src/panicking.rs:48:5
	   3: fox32asm::parse_data
	   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.
