Linker Script parser

ldparser's Issues

Upgrade to `nom` 7.1.3

Hi,

I find this crate very helpful. However, this crate is using a somewhat outdated version of nom. If you run cargo fix, you will see a warning:

warning: the following packages contain code that will be rejected by a future version of Rust: nom v3.2.1

Therefore I have managed to upgrade the nom version used in this crate to 7.1.3, which is the latest version. I have passes all the tests and checked that the parser generates the same output. You can checkout my fork here: https://github.com/VoodooChild99/ldparser/tree/upgrade-nom. I can open a PR if you are interested.

`INSERT BEFORE/AFTER` support

This crate has been incredibly useful for testing linker script fragments. Unfortunately, I seem to have run into some limitations.

Is it possible to INSERT BEFORE/AFTER functionality, so that I can test for equality against this crate's types instead of strings?

Support for 'K' and 'M' suffixes for integer constants

I've successfully used this parser with linkerscript that define constants in hex format, but it will fail with an equivalent 'human-readable' text format.

Additionally the suffixes K and M may be used to scale a constant by respectively. For example, the following all refer to the same quantity:

   _fourk_1 = 4K;
  _fourk_2 = 4096;
  _fourk_3 = 0x1000;

source: https://ftp.gnu.org/old-gnu/Manuals/ld-2.9.1/html_chapter/ld_3.html#SEC8

For reference, I was specifically using those in the MEMORY section, e.g.:

MEMORY
{
bootloader (rx) : ORIGIN = 0x08000000, LENGTH = 0x020000
FLASH (rx)     : ORIGIN = 0x08020000, LENGTH = 0xE0000
}

this will parse successfully

vs

MEMORY
{
bootloader (rx) : ORIGIN = 0x08000000, LENGTH = 128k
FLASH (rx)     : ORIGIN = 0x08020000, LENGTH = 1M - 128k
}

which won't

I will post minimum reproducible example later
