Change sic1d07 to letters

[HSalat]

The population data loaded by SPC has letters for sic1d07, while the business registry has numbers (A = 1, B = 2, etc.). This means that there is a conversion happening somewhere during the commuting modelling. The new business registry will have a letter directly. The code needs to be adapted accordingly.

For ref, the new businessRegistry.csv.gz.

Note that Ids have changed slightly.

As you mention the letters run from A-U it's probably easiest to use a char instead of the current u32. We could also add a type Sic1d2007 = char; for clarity. Happy to implement this.

@dabreegster is best placed to confirm which parts of the code should be changed

[dabreegster]

What exactly is the ask here? The output proto is already a letter:

uatk-spc/synthpop.proto

Line 115 in 108794b

// The Standard Industrial Classification of Economic Activities 2007, 1st

Is businessRegistry.csv changing? If so, then a small amount of code changes internally. See

uatk-spc/src/init/commuting.rs

Line 75 in 108794b

sic1d2007: u32,

and

uatk-spc/src/init/commuting.rs

Line 274 in 108794b

/// Turn "A" into 1, "B" into 2, etc

Edit: I didn't read clearly -- so the registry csv is changing. Should be a very easy change in this code
