- Add tables/data to represent our .data segment - Add compiler/main/analyzer/data to extract string literals - Emit .data section with symbols and data for the strings - Adjust examples/assert_examples.sh to not check for newline at the end of file. Since struct StringConst does not support this right now.
✅ Deploy Preview for espl1000 ready!

Previously, 2 distinct strings could be mapped to the same symbol. This should hopefully not happen now.
Instead of hardcoding (just done for PoC), define a function 'data_string_offset' to return the offset in DataTable for a string.
oopsie, must have accidentally copied that. Unused file, builds without that.
This is so that they can be passed into functions expecting C strings which are NULL-terminated. - fix tac/tac_str.c to print width of load/store. - fix examples/syscalls/read_file/read_file.dg to read from it's own source file and print the first few chars. Also add a .stdout file there so it gets picked up by the test suite.
Propagate the escaped chars into the assembly. NASM supports these when the string appears in backticks [1]. References: [1] https://www.cs.ubbcluj.ro/~vancea/asc/practic/nasm_html/nasmdoc3.html
