jn 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:

	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.

fox32asm

fox32asm is a work-in-progress assembler for fox32.

Getting Started

Stable releases are available on the Releases page.

Prebuilt binaries of the latest commit are also available on the GitHub Actions page.

Usage

fox32asm expects arguments in the following order: fox32asm <input> <output>

<output> should end in the file extension .fxf if building a relocatable FXF binary, otherwise a raw binary will be generated instead.
